Chapter 7. A Long Farewell to Peoria

Peoria was the "crucible" and proving ground where Elias Cooper gained professional experience and maturity. During the decade from 1844 to 1855 he worked tirelessly to improve his knowledge of anatomy and his mastery of surgery. Literally, there was "no day without a line." Like Daniel Drake and many other leaders of American Medicine in his day, he overcame formidable educational and other handicaps by relentless personal effort. With Drake he shared the firm belief that "labor omnia vincit" and, in later years, he made this the theme of his exhortation to medical students in California.

Peoria's historians write of Cooper as the leading surgeon of the city. "Large, powerful, earnest, vigorous and sensitive, he thought, talked and wrote only of surgery, begrudging even the few hours he slept daily as time lost from his work".[1]

By all accounts he was single-minded and dedicated. He demonstrated uncommon enterprise and courage by conducting Anatomy Courses regardless of public censure in Peoria from 1848 to 1855. He competed creditably against considerable odds in the Anatomy Concours at Rush in June 1850. He attended a 4 1/2 month course of medical lectures in 1850-51 at St. Louis University where he finally received an MD degree in March 1851. And he founded Peoria's first hospital entirely at his own expense in September 1851. Meanwhile he developed an extensive surgical practice where he introduced innovative and advanced procedures to which we shall later refer. In his eagerness to expand his specialty practice and attract patients with eye and orthopedic disorders to his hospital, he advertised his services and the hospital in newspapers in the region. For this, his medical society colleagues accused him of unethical conduct, a subject to which we shall shortly return.

Cooper recognized the significance of the National Medical Conventions of 1846 and 1847 that founded the American Medical Association and stimulated the formation of state and local medical societies throughout the country. He had an abiding faith that such organizations were the best hope for raising medical standards and improving relations among physicians. This conviction led him to participate zealously in the founding of medical societies in Illinois and California. Understandably, he was dismayed when fellow society members, first in Illinois and later in California, accused him of unethical conduct for "advertising" his hospital and specialty practice. Throughout his career Cooper's medical ethics were questioned on one pretext or another by detractors whose often-spurious charges cast a still-lingering shadow over his reputation. Recently, however, we have discovered transcripts in his own hand that explain his actions and respond vehemently to his critics. When in the course of our continuing narrative the question of ethics arises, as it frequently will, these new findings should help us to understand, and possibly even accept, his point of view.

Advertisement for Cooper's Hospital

We cannot be certain when Cooper began to place advertisements for his hospital in regional newspapers but can assume from subsequent events that it was probably in the fall of 1851, shortly after the opening of his institution. The following advertisement, published in the Peoria Weekly Republican on 23 July 1852, is the earliest copy of the ad available.[2]

and Orthopedic Establishment

The undersigned having purchased and enlarged the house known as the English cottage on Monson and Sanford's Addition to the City of Peoria, designs it as a permanent place for the treatment of all persons afflicted with Eye Diseases, and those desirous of undergoing examinations for the cure of all deformities such as long standing dislocations, club foot, immobility of the lower jaw, etc.

The building is in a healthy and beautiful location where patients can be accommodated with comfortable rooms, boarding and nursing such as corresponds with the desires of each case. Every instrument is provided, and in the Orthopaedic department, several entirely original ones are used, some of which in the club feet of young children, frequently obviates the necessity of operating with the knife. For further information address

E.S. Cooper, M.D.
Peoria, Ill.

Hon. S. A. Douglas, Chicago
Hon. A. Lincoln, Springfield, Ill.
(and names of 25 other persons).

Not reticent to claim the support of prominent citizens for his institution, Cooper appended a list of 27 References to his advertisement. The list included many high officials in Illinois State government as well as other notables from Ohio to Iowa. Most memorable of the references are Stephen A. Douglas, U.S. Senator from Illinois at the time, and Abraham Lincoln, an attorney at Springfield, who had served as an Illinois Representative to the U.S. Congress from 1847 to 1849. Lincoln had been elected to Congress as a member of the Whig Party which was superseded by the new Republican Party organized in 1854 to oppose the extension of slavery. Lincoln joined the Republican Party and became its successful candidate for the U.S. Presidency in 1860. There is no evidence among Cooper's papers to prove that he was acquainted with Abraham Lincoln or any of the other political figures listed as references. On the other hand, it is doubtful that even the brash Cooper would have used their names in a published advertisement without some personal link with them. It could be that Cooper was much more active in State and regional politics than we are aware. We have only one tantalizing clue. A simple notice was published in the Peoria Weekly Republican for 7 May 1852. It read: "(Dr. Elias Cooper was) at Whig meeting." Why should Cooper's presence at a meeting of the Whig political party be newsworthy? We must add this to the many unanswered questions about his personal life.[3]

A.M.A. Code of Ethics on Advertising, 1847

In the mid 1800s medical ethics was a highly sensitive issue among physicians. Since the self-confident and aggressive Cooper was destined frequently to test the boundaries of ethical practice, and provoke harsh criticism for his temerity, it will be useful for us to consider the status of American medicine and the attitude of the profession toward medical ethics in his day.

When the second session of the National Medical Convention convened in Philadelphia in 1847 it not only founded the American Medical Association but also passed a number of important resolutions. The Fourth Resolution stated: "That it is desirable that a uniform and elevated standard of requirements for the degree of M.D. should be adopted by the Medical Schools of the United States." This resolution was the basis for the A.M.A.'s continuous struggle to induce American medical schools to raise their standards, an effort frustrated over the next 60 years by the self-serving intransigence of the majority of the schools. General reform in medical education did not finally occur until after Flexner's fearless critique of 1910, to the preparation of which the A.M.A. lent its valuable support.[4][5][6]

When the Fourth Resolution was framed in 1847, the parlous state of the medical profession was much on the minds of the delegates:[7]

The very large number of physicians in the United States, a number far larger in proportion to its population than in any other country perhaps of which we have a correct knowledge, has frequently been the subject of remark. To relieve the diseases of something more than twenty millions of people, we have an army of Doctors amounting by a recent computation to forty thousand, which allows one to about every five hundred inhabitants. And if we add to the 40,000 the long list of irregular practitioners who swarm like locusts in every part of the country, the proportion of patients will be still further reduced. No wonder, then, that the profession of medicine has measurably ceased to occupy the elevated position which once it did; no wonder that the merest pittance in the way of remuneration is scantily doled out even to the most industrious in our ranks, - and no wonder that the intention, at one time correct and honest, will occasionally succumb to the cravings of a hard necessity. The evil must be corrected. With a government like ours, to diminish the number of medical schools is not to be expected; and the corrective can alone be found in the adoption of such a standard of requirement. . . as will place the diploma beyond the reach of those who seek to wear its honours without deserving them.

The National Convention's Sixth Resolution, also relevant to Cooper's future, asserted: "That it is expedient that the Medical Profession in the United States should be governed by the same code of Medical Ethics."[8] Convinced that high ethical standards were vital to improvement of medical practice and the status of medicine, the National Convention drew up a comprehensive ethical code for the A.M.A. and, in due course, each state and local medical society adopted a code of ethics comparable to it. The Illinois State Medical Society of which Cooper was a founding member was organized at a Medical Convention in Springfield in 1850. On that occasion the Convention accepted the A.M.A. code with slight modification of the section on advertising. The following is the Illinois version of the section on advertising which Cooper was accused of transgressing:[9]

It is derogatory to the dignity of the profession, to resort to public advertisements or private cards or handbills, inviting the attention of individuals affected with peculiar diseases - publicly offering advice and medicine to the poor gratis, or promising radical cures; or to publish cases and operations in the daily prints, or favor or encourage such publications, except in approved medical prints; to invite laymen to be present at operations,- to boast of cures and remedies, - to adduce certificates of skill and success, or to perform any other similar acts. These are the ordinary practices of empirics, and are highly reprehensible in a regular physician.

During the Colonial period and throughout the 19th century American physicians were on the defensive against irregular practitioners who indeed swarmed "like locusts, " especially in newly settled regions of the country such as the Old Northwest. The irregulars were, to say the least, unconstrained by any ethical principles. Government regulations and licensure requirements were either non-existent or unavailing. On the other hand, the medical profession itself took no substantial steps toward self-improvement because the majority of medical schools were unwilling to raise their standards. As a result, public opinion was ambivalent regarding even regular medical practitioners in the mid 1800s. Another reason for the public's disaffection was that physicians often had little more to offer than did the botanics, sectarians, cultists, eclectics, electric healers, mesmerizers, hydropaths and other quacks. In fact, the punishing regimes that at mid century still often included bleeding, purging and calomel led many patients to believe that they were unsafe in the hands of the regular physician.[10]

Under these circumstances, one of the profession's most effective means for distinguishing the regular from the irregular practitioner was the ban on advertising, and medical societies were committed to its strict enforcement. Given the contentious spirit latent in the medical fraternity, abundant manifestations of which we have already seen, it is not surprising that there was self-righteous vindictiveness in the persistence with which Cooper's enemies in the Peoria and Illinois State Medical Societies pressed a case against him for "advertising" his hospital.

The following chronological account of Cooper's role in these Societies will bring to light important features of his career in Peoria not yet addressed, and will provide background for our consideration of the dispute over ethics in which he became embroiled.

Founding of Peoria Medical Society
19 April 1848

Peoria doctors were among the first, if not the first, in Illinois to organize a stable and continuing local medical association. They formed a medical society in 1846, reorganized it in 1847 and finally established a permanent society on 19 April 1848. It was on the evening of this latter date in the office of Dr. Frye - a dingy little room with a pine floor and three or four stuffed wooden chairs - that the following six physicians met by candlelight to found an association known originally as the Peoria Medical District Society:[11][12]

  • Elwood Andrew
  • J.C. Frye
  • John D. Arnold
  • F.A. McNeill
  • Edward Dickinson, Chairman
  • J. Murphy, Secretary

Dr. Zeuch, historian of the early days of medical practice in Illinois, writes that "seven men met to organize the first medical society in Peoria County" and he names Cooper as the seventh man. Nevertheless, the account of the organizational meeting of 19 April 1848, recorded longhand in the Minute Book of Peoria Medical Society, states that the founding group consisted of only the six physicians named above - and Cooper was not among them.[13]

Although it appears that Cooper may not have been a founding member of Peoria District Medical Society, we do find him present only seven weeks later on 6 June 1848 when 30 members convened at Peoria in the First Annual Meeting of the Society. During that meeting Cooper was appointed to membership on the Standing Committee on Medical Statistics. It was on this occasion that Cooper was initiated into the mysteries of medical society organization which remained a fatal attraction for him the rest of his life. In this particular aspect of professional affairs, he was ever after intensely involved.[14]

This leads us here to the further observation that Cooper was never married and his records contain little information about his social life, apart from interaction with his own family and his ardent participation in medical societies.

There were several features of the First Annual Meeting of the Peoria Society that attest to the alertness of its members and the extensive region of the country over which they were scattered: (1) E.M. Colburn of Bloomington (40 miles southeast of Peoria) made a report on the use of ether in obstetrics practice (only a year and a half after its introduction as an anesthetic), and was elected President of the Society for the ensuing year; (2) the Society adopted the Code of Ethics of the American Medical Association which had been formulated only a year previously at the National Convention in Philadelphia. Among those present at the meeting were the men who later charged Cooper with unethical practice: Drs. John D. Arnold of Peoria and Dr. Thomas Hall of Toulon (30 miles northwest of Peoria). This is an opportune moment to introduce them and through their lives gain some additional insight into medical practice in Illinois at mid-century.

John D. Arnold, MD (1820-1863)

Sketches of Doctor Arnold's early life by historians of Peoria County are contradictory and create uncertainty as to the facts. He was born 8 June 1820 in the small town of Collins, Erie County, New York, 15 miles south of Buffalo. He probably began the study of medicine in 1840 as an apprentice to a practitioner in Buffalo. According to the annual Buffalo City Directory, Arnold was a "Medical Student" with M.W. Hill, a "Botanical Doctor," in 1840 and 1841. He attended Allegheny College in Meadville, Pennsylvania, as a Preparatory Student for one year in 1842. He was enrolled as a first year college student for part of 1843 before dropping out. He appears only once more in the Buffalo City Directory in 1844 when he is listed simply as a "Medical Student."[15][16]

If and where he received an MD degree are unclear. The History of Peoria County records that he "attended for a considerable time the New York College of Surgeons;" that "he commenced the practice of Medicine at Springville, New York, with Dr. Emmons;" and that "in the Spring of 1847 he emigrated to Galveston, Texas, remaining there but one year, when he removed to Peoria and resumed the practice of medicine. . . "

The actual date of Arnold's arrival in Peoria is unknown although it was obviously prior to April 1848 because he was sufficiently established in practice by that time to be included among the six physicians who organized the Peoria District Medical Society. He was not a founding member of the Illinois State Medical Society that first met in Springfield in 1850, but he became a member of that Society when it convened in Peoria in 1851 for its First Annual Meeting. On that occasion he was listed as a delegate from the Peoria Medical Society.

Presumably he was primarily engaged in general practice as were virtually all physicians in Peoria, but it is evident from his appointment to the State Society's Committee on Surgery in 1853 that he also did some operating. This would have put him into competition with the hard-driving Cooper who considered himself a specialist in surgery and scorned dilettantes in his field, as he would have deemed Arnold to be.

A tall, slender man of a lively social turn of mind, Arnold is said to have enjoyed the esteem and confidence of all with whom he came in contact, and was rewarded by a flourishing practice. He had a delicate constitution and throughout his adult life suffered from what would now be termed latent tuberculosis. His tastes ran more to political affairs than to the intricacies of medical science, and this was reflected in his approach to professional matters. In fact, as his career unfolded, his interest and forte proved to be not medicine, but politics. He was a Whig and, when the Party dissolved, he cast his fortune with the Republicans. He campaigned for public office and in 1854 was elected to the Illinois State Senate where he served four years. In 1859 he was elected mayor of Peoria and served one year. During the 1840s and 1850s Abraham Lincoln emerged as the "wheelhorse" of the Whig and Republican Parties in Central Illinois and Arnold became his personal friend. This led in 1861 to Arnold's appointment by President Lincoln as Consul to St. Petersburg, Russia. Arnold left Peoria for his foreign post in May 1861. When the rigors of the Russian winter proved too severe for his fragile health, he was forced to return to Peoria in the spring of 1862. There, after a protracted illness, the Honorable John D. Arnold died of consumption in April 1863 at the age of 43.[17][18][19][20]

Thomas Hall, MD, (1805-1876)

According to a schoolteacher who was raised on a small farm north of Peoria, the country around the homestead where her family settled in 1838 was a wasteland broken only by distant groves of trees. She recalled that:[21]

In the early '40s, the roads by which the settlers occasionally passed from one grove to another were faint trails, sometimes almost overgrown and hidden by the luxuriant grass of the prairie. And the sloughs, as the feeble watercourses were called, were unbridged, so that in spring season or time of heavy rains many of them were impassable.

The nearest physician lived . . . 18 miles away in the village of Osceola. He was an Englishman. . . No man ever more adorned the profession of healing. He rode in what he called his "pill-cart," night and day, in all weathers, from hamlet to hamlet, prescribing for the sick, supplying them medicines, setting broken limbs, and delivering pregnant women. His patients paid when they could, and how they could. A load of hay, or corn, or firewood, or a quarter of venison, or a horse to supply the wear and waste of his stable. He never considered the question of gain, and I doubt if he ever sent a bill to a single patient.. . . He died a poor man, followed to his grave by the tears and affectionate remembrances of three generations. His name was Thomas Hall.

According to local tradition, one of the first settlers on Spoon River in what is now Stark County was a very religious man. He had great faith in the power of prayer, but he was also a practical man and never asked God to do the impossible. Among his petitions to the Almighty was the fervent request that a doctor be sent to the settlement where he and his family lived; that the doctor would be devoted to his work and labor for the benefit of the people; and that he would be accompanied by a well-educated wife who would be interested in the wives and daughters of the settlers. When in 1837 Dr. Thomas Hall arrived on the Illinois frontier, bringing with him his wife and family from England, it was regarded as undeniably an answer to the old settler's prayer.[22]

Doctor Hall was born on 12 March 1805 near Hulland in Derbyshire, England, where he attended a local grammar school. Following apprenticeship under a practitioner in neighboring Stafford County, he studied at the Royal College of Surgeons in London, graduating as a doctor of medicine and surgery in 1828. His diploma bore the names of Sir Astley Cooper and Dr. John Abernethy, two of the best known medical men in England at the time. "When the young Dr. Hall was leaving home to begin life and practice for himself, his good mother followed him to the gate, and laying her hands lovingly on his shoulder said to him 'Tom, do your duty by all, but especially remember the poor'."[23]

After nearly ten years of active and successful practice in his native county of Derbyshire, Dr. Hall had a wife and four children, and a desire to seek a new home for them on the American frontier in Illinois where two brothers and a sister had settled the year before. In 1837 he embarked for America, the land of promise, accompanied by his own family, his father and mother, and his sister, her husband and their five children. Overcome by sea sickness on the Atlantic, his mother died a few days before the ship reached New York and was buried at sea. An exhausting and hazardous journey inland still lay ahead for the sorrowing party of five adults and nine children. They traveled northwest by boat up the Hudson River; by way of the Erie Canal, and Lake Erie to Cleveland, Ohio; thence by boat on a canal to the Ohio River; and, from there, down the Ohio, and up the Mississippi and Illinois Rivers to Peoria, then only a hamlet on the west bank of the Illinois River where it widens to form Lake Peoria. The final stage of the odyssey, by horse and ox-drawn wagons, brought them to a happy reunion with Dr. Hall's brothers and sister at the frontier settlement of Osceola, 35 miles north of Peoria. The settlement was in open country later to become Stark County.

Assisted by his brothers and his father, Hall built a log cabin for his family including an office for himself. At the age of 32, and having "brought with him a library of choice medical works and surgical instruments of the most approved pattern then known to meet every emergency," he began the practice of his profession without delay. In 1842 he moved with his family ten miles south to the village of Toulon which had become the county seat, and from there he continued his peripatetic practice. We have already learned of the respect and affection in which he was held by his patients. He continued to serve them until incapacitated by the infirmities of age. Only a few days before his death he remarked to some of his friends, "I am not afraid to meet my mother, for she knows that I have done as she told me." Here was a man whose criticism Cooper was bound to respect.[24]

Cooper's First Scientific Paper

Cooper found in the Peoria and the State Medical Societies a welcome forum for the scientific papers that he now began to produce regularly.

We have already mentioned the first publication of his career, a paper entitled "Remarks on Congestive Fever" printed in 1849, on which paper he prematurely listed himself as "E.S. Cooper, M.D.," two years before he actually received a medical degree from St. Louis University in 1851. He presented a second paper, entitled simply "Congestive Fever," at the Peoria Medical Society and published it in 1850. Since both these papers were reviewed at the First Annual Meeting of the Illinois State Medical Society in 1851, we shall defer comment on them until we take up Cooper's participation in that meeting.

We learn from the Minutes of the Peoria Society that Cooper was a frequent contributor to their scientific program. His topics were:[25]

  • 1850 -Congestive Fever
  • 5 Dec 1852 - Diseases of the Eye
  • 7 Jan 1853 - New Operation for Congenital Scrotal Hernia
  • 20 Feb 1853 - Treatment of Vaginal Ulceration
  • 5 Mar 1853 - Surgery of Oceanea as Practiced by Natives
  • 16 Jul 1853 - Surgery of the South Sea Islands
  • 1 Apr 1854 - Treatment of Diseases of Hip Joint

As far as we can determine none of these presentations, except for that on "Congestive Fever," was ever published. They are listed here primarily to illustrate the range of his interests at the time and the fact that he enthusiastically supported the educational efforts of the new Society. We shall return to consider the disciplinary action taken against him by the Peoria Medical Society after we have reviewed his substantial contributions to the early history of the State Society, beginning with the Medical Convention at which the Society was founded.

Medical Convention for the Purpose of Organizing the Illinois State Medical Society, Springfield, Illinois, 4 June 1850

The American Medical Association at its Second Annual Meeting, held in Boston in May 1849, adopted the following resolution:[26]

Resolution 5. Resolved, That in accordance with a resolution of the American Medical Association, adopted May 4th, 1847, "it is earnestly recommended to the physicians of those States in which State Medical Societies do not exist, that they take measures to organize them before the next meeting of this Association."

In response to Resolution 5, the doctors of Illinois responded decisively. Forty-nine physicians from around the State assembled in a Medical Convention in Springfield, the State Capitol, on 4 June 1850. On the first day of the meeting, under the presidency of Rudolphus Rouse of Peoria, the Convention proceeded with clockwork precision to resolve into a Committee of the Whole; ratify a Constitution; declare itself the Illinois State Medical Society; elect officers for the ensuing year; appoint Standing Committees; and adopt a code of Medical Ethics based on that of the A.M.A. By any standard, a remarkable day's work.[27]

While engaged in these heady organizational proceedings, Cooper was uncomfortably aware that he had not yet obtained an MD degree, or even attended a medical school (although, as we have seen, he had been signing himself as "M.D." since 1849). His position in this regard was now quite untenable because of the following resolution that had also been adopted by the A.M.A. at the Boston meeting in 1849:[28]

Resolution 6. Resolved, That the State Societies be recommended, after they shall have been organized, to recognize as regular practitioners none who have not obtained a degree in medicine, or a license from some regular medical body, obtained after due examination.

The Transactions of the recently established A.M.A. were of extraordinary interest to the medical profession. Thus there can be no doubt that Resolution 6 came promptly to Cooper's attention and that he grasped the importance of his obtaining a legitimate MD degree as soon as possible. Accordingly, he took the steps necessary to acquire an MD ad eundem from St. Louis University in March 1851, just in time to avoid an embarrassing exposure by the strict constructionists of the Illinois State Medical Society at the forthcoming First Annual Meeting.

Cooper was one of the 49 founding members of the State Society. During the organizational meeting he was appointed to the Society's Standing Committee on Surgery, chaired by the dean of Illinois surgeons, Professor Daniel Brainard of Rush. Appointment to membership on this three-man surgical committee was a significant mark of recognition for the 30 year old Cooper. He was also named to the important Standing Committee on Arrangements which was charged with preparing for the First Annual Meeting of the Illinois State Medical Society to be held the following year in Peoria.

In order to trace Cooper's further involvement in the affairs of the Illinois State Medical Society, we shall summarize his participation in each of the annual meetings from 1851 through 1854.[29]

First Annual Meeting of Illinois State Medical Society
Peoria, Illinois, 3-4 June, 1851

Cooper was a member of the Committee on Arrangements that organized the program for this First Annual Meeting of the Society. During the meeting he was elected as an Alternate Delegate to the next meeting of the American Medical Association.

Also during the meeting Cooper proposed the following Resolution on Dissection to which we referred earlier:

Whereas, The present laws and public sentiment of the people of the State of Illinois are strict and binding, holding the Physician and Surgeon legally responsible for the performance of their duty, but at the same time are hostile to those means by which a practical knowledge of pathology, skill, and surgical anatomy is obtained; therefore

Resolved, That a Committee of three be appointed to investigate the subject of legal dissections in all it relations and bearings, and report the same to this Society at its next annual meeting.

The preamble and resolution were adopted and the following gentlemen were appointed as the Committee on Legalizing Dissections: Drs. E.S. Cooper (Chairman), J.C. Frye and William Chamberlain.

Two of the earliest scientific papers to be published by Cooper in a medical journal were reviewed at this meeting by the Society's Committee on Practical Medicine in an "elaborate report" read to the assembled Society, which must have been very gratifying to the author. The first of these two papers, entitled "Remarks on Congestive Fever," was published in two parts in the St. Louis Medical and Surgical Journal in 1849 and 1850. The paper is a report of three fever patients two of whom died. One of the deceased was autopsied by Cooper and the findings are reported. The second paper, entitled "Congestive Fever," was published in the North-Western Medical and Surgical Journal for November 1850 and is a report of three additional fever patients, one of whom died but was not autopsied. All six of Cooper's patients, diagnosed by him as suffering from "Congestive Fever," undoubtedly had malaria, the endemic pestilence that ravaged Illinois during Cooper's era, as we previously discussed. Being of unknown origin at the time and often fatal, speculations as to the cause and management of malaria were the subject of innumerable journal articles and textbook discussions that consisted chiefly of futile theorizing as to etiology and of frustrated groping for effective therapy.[30][31]

Cooper's finding of venous engorgement in brain, heart, lungs and liver of his autopsied patient, whom he diagnosed as having died of "Congestive Fever," convinced him that "general internal venous congestion" was specific to the disease. This was a common hypothesis at the time and led to the frequent use of blood-letting to relieve the "congestion" as a primary mode of treatment, as we have seen. Quinine was not yet recognized as the ultimate specific for malaria. Nevertheless, it was being generally accorded a regular but rarely exclusive role in therapy. Cooper's regime in the autopsied patient had consisted of "brandy, quinine, camphor, calomel and morphine, in large and frequent doses; mustard poultices extending from ankles to knees and from wrists to elbows; bottles of hot water to the sides; and a large quantity of bruised horseradish to the region of the stomach and bowels. The pulse rose a little, and the skin became somewhat warmer under this treatment, but (the patient) died in a few hours."

Cooper's inclusion of large doses of quinine, and his exclusion of blood-letting and purging, in the treatment of his patients are the most notable features of his papers. They otherwise consist of tortured reasoning about the relationship of different degrees of "internal venous congestion" to various clinical manifestations of "congestive fever." For example: "Symptoms vary, owing to the part or parts which may be the seat of congestion, and the internal remedies have to be modified accordingly - thus in congestion of the veins of the liver and mesentery, there will be vomiting and purging; and should these organs be the principal seat of congestion, quinine would be of little avail during the paroxysm. The remedies in this case, should be calomel and opium, with brandy and the application of hot air, etc., etc."

Deficiencies in medical knowledge and practice in the mid 1800s as compared to the present are once again cited here not to belittle the doctors but to enable us to understand the difficulties they faced, and to entertain the thought that present-day physicians, provided with only their limited information and resources, would have responded to conditions much as they did. When Cooper boldly addressed the "fever question," the foremost medical problem of the period, he had never taken a course in a medical school. If he had, it would have made no difference to the outcome in his patients, except that he probably would have harmed them further by insisting on bloodletting.

Cooper's Paper on Chloroform

Professor Brainard and the other member of the Standing Committee on Surgery failed to arrive at the Society meeting. Therefore, Cooper was called upon to make a report for the Committee, which he was happy to do. He had wisely brought with him a scientific paper he hoped to get on the program if time allowed. His presentation was on a subject far more congenial to his interests than "Congestive Fever." He spoke on the topic of "Chloroform in Surgical Operations."

At the time of the State Society meeting in 1851, general anesthesia was a recent innovation. Ether had been administered by a dentist, W.T.G. Morton, for an operation performed by Professor Warren at the Massachusetts General Hospital in October 1846. A year later, chloroform was introduced for childbirth by Professor Simpson at Edinburgh in November 1847.[32][33]

There was immediate worldwide interest in these agents and reports of their use in childbirth and surgery promptly appeared in the medical journals of the Old Northwest. Cooper at once recognized the immense significance of these developments and was among the earliest in the region to experiment with general anesthesia. He reported that he "had an opportunity of testing the effects of Chloroform as an anaesthetic agent in seventy-nine cases of Surgical operations since the organization of the State Medical Society (in 1850)." He pointed out that, although most of the operations were minor, they nonetheless demonstrated the effectiveness of chloroform in producing insensibility. He further stated that, although there were no fatalities in his series of cases, a complication occurred in one patient which was the principal reason he decided to report on the subject of chloroform anesthesia. He then went on to describe the following harrowing incident:[34]

Case. - Mrs. M.C., a widow lady aged 25, of good constitution and decidedly vigorous health, took Chloroform for the purpose of undergoing an operation for Strabismus, Dec. 10, 1850. She was seated in a chair, and the Chloroform given under my directions. About twenty drops were used, and the napkin containing it held close to the mouth wide open. Two or three vigorous inhalations were rapidly made, when the patient sank down, and would have fallen at my feet, had not support immediately been afforded her. She struggled, gasped for breath, became pulseless while the lips and cheeks assumed a purple hue.

I placed her in a recumbent position, forcibly expanded the lungs, titillated the fauces, sponged the face with spirits of camphor, and exhibited some of the same internally.

After recovering from the immediate symptoms, which she was slow in doing, great head-ache, pains and fullness in the chest, together with a stunned and torpid condition of the sensorial powers, with considerable prostration of physical strength remained for some days.

Cooper's patient had suffered a cardiac arrest due to the paralyzing effect on the heart of chloroform administered in too high a concentration. He correctly inferred that the risk of this disastrous cardiac complication could be minimized by gradual administration of the agent while always assuring ample inspiration of room air. To test this conclusion, he later recalled Mrs. M. C. whose operation for strabismus he then performed without incident under chloroform anesthesia delivered in accordance with the above precautions.

The significance of Cooper's paper lies in his warning of the lethal potential of chloroform, then being widely and indiscriminately used by inexperienced practitioners. Soon after Professor Simpson's report in November 1847 "On an anaesthetic agent, more efficient than sulfuric ether," chloroform was being hailed In Europe and America as the agent of choice for general anesthesia in preference to ether, over which it indeed had many advantages. Ether is irritating to the air passages; has a disagreeable and lingering odor; is highly flammable; and is slow in action. On the other hand, chloroform is well tolerated by the airways; has a not unpleasant odor, is not flammable; and is ten times as potent as ether. Yet, ominously, within a few months of the introduction of chloroform, reports of sudden death during its administration for minor operations began to come in from around the world. First, in January 1848, a girl of 15 at Newcastle-upon-Tyne suddenly collapsed and died during removal of a toenail; next, in February 1848, a woman of 35 in Cincinnati died during extraction of teeth; then a young woman in Hyderabad died during excision of the end of a finger; followed by death of a woman aged 30 at Boulogne; a man from Glasgow; a boy of 17 at Lyon, and a laboring man at Westminster. These patients were cited in a classical paper "On the fatal cases of inhalation of chloroform" by Queen Victoria's anesthetist, Dr. John Snow of London, the first physician to devote his full time to the practice of anesthesia. Snow's sobering article was published in the Edinburgh Medical Journal in July 1849, just over a year and a half after the introduction of chloroform.[35]

Although Snow demonstrated by personal experience that chloroform could be administered with relative safety by controlling the dosage of the vapor with a suitable inhaler, its deadly potential for arresting the normal heart led within a decade to its progressive decline in favor. Ether then became for many years the agent most widely used for general anesthesia until replaced by better drugs. As for Cooper, he continued to prefer chloroform until ten years later in 1861 when he wrote:[36]

The announcements of deaths from the use of Chloroform are becoming truly frightful. Scarcely a medical journal reaches us without containing the account of some recent death by Chloroform. We were once a very strong advocate of its use, but experience has taught us that it is absolutely unsafe when inhaled to the extent of producing insensibility to pain. So we seldom use it now, except in cases of a desperate character.

A myth has grown up that attributes to Cooper the first use of chloroform for surgical anesthesia in the Old Northwest, but Cooper himself made no such claim.[37][38] In fact there is no record of the specific dates on which his operations were performed. He stated in his paper that his 79 cases had been done "since the organization of the State Medical Society." That is, after 1850. From a review of regional journals it seems likely that both Professor Brainard of Rush in Chicago and Professor Mussey of Ohio Medical College in Cincinnati both used ether and chloroform well before 1850, and were the first to administer these agents for surgical anesthesia in the Old Northwest.

Professor Brainard first used ether anesthesia when he performed two surgical procedures - amputation of a finger and resection of metatarsals - in January 1847, only 3 months after the introduction of ether at Boston in October 1846.[39] In a second report, published in October 1847, Brainard said that "We have lately used (ether) for the extirpation of two cancerous breasts, extirpation of tumors, opening of abscesses, strabismus, etc., with most satisfactory results."[40]

With respect to Brainard's use of chloroform, it was reported in December 1847, only one month after this agent was introduced in Edinburgh, that he had already performed several operations under anesthesia with chloroform which had been manufactured by Professor Blaney in the laboratory at Rush Medical College.[41]

R.D. Mussey, Professor of Surgery at Ohio State Medical College, reported in September 1848 that he had "employed etherization in the amputation of all the members belonging to the human body" and various other operations such as excision of tumors, lithotomy and reduction of dislocations. Regarding his use of chloroform, Mussey said that soon after the announcement of Dr. Simpson's experiments with the agent had reached him, he proceeded to try it without hesitation in 38 surgical operations, and saw no unpleasant reaction in a single instance. The operations performed under chloroform included such procedures as removal of tumors, amputations, strangulated hernia, etc. Mussey cited the deaths from chloroform at Newcastle-upon -Tyne and Cincinnati to which we have already referred and attributed them to improper procedures in administering the agent. "On the whole", he concluded, "I regard the inhalation of chloroform for surgical operations, administered with due precaution, as entirely safe; and I look upon it as a boon of inestimable value, presented by Chemistry to our profession under the guidance of Providence."[42]

These references to the use of ether and chloroform by Drs. Brainard and Mussey illustrate the rapidity with which the agents were incorporated into surgical practice even in the relatively undeveloped western section of the country. The evidence suggests that these two Professor of Surgery in the leading medical schools of the Old Northwest were the earliest to employ ether and chloroform in the region and that Cooper was not, as local tradition would have it, the first in the area to use chloroform. Nevertheless, Cooper's substantial series of 79 patients operated under chloroform anesthesia in the provincial town of Peoria, and his timely emphasis on the agent's lethal properties, bespeak his capacity for leadership in the new era of surgery that began with the advent of general anesthesia.

Cooper's presentation on chloroform anesthesia at the first annual meeting of the State Society was the only scientific paper delivered during that meeting at the initiative of an individual member.

Second Annual Meeting of Illinois State Medical Society
Jacksonville, Illinois, 1-3 June 1852

Elias Cooper attended this meeting of the State Society as an elected Delegate of the Peoria Medical Society. On the first day of the meeting Levi Cooper Lane from Henderson, was elected a Permanent Member of the State Society on the recommendation of his Uncle Elias, thus establishing Lane's presence in Illinois in 1852.

As evidence of increased recognition of Cooper within the State Society, we find him appointed during this meeting to the Committee on Unfinished Business; to the Nominating Committee for Society Officers for the ensuing year; and to the Committee on Surgery for the ensuing year. He was also elected as First Secretary of the Society for the ensuing year, and as a Delegate to the A.M.A. at its next meeting to be held in New York in May 1853.

When Cooper was called on to report for the Committee on Legalizing Dissections, he pointed out that the Committee was charged to memorialize the Legislature rather than to submit a report to the Society. As already noted, we have no information on the steps the Committee may have taken to influence the Legislature. In any case no legislative action was taken on this subject until years later.

Cooper and Levi Cooper Lane were the only members of the Society, except those submitting reports of Standing Committees, to present papers on their personal scientific observations. Lane was unable to attend the meeting and Cooper read his paper for him. The papers by Cooper and Lane, published as Appendixes of the Transactions, are summarized here briefly to indicate the modest level of scientific communications at the meeting.

Appendix B. "Collodion in Entropion" By. E.S. Cooper, M.D.

Entropion is inversion or turning inward of the margin of the eyelid bringing the eyelashes into contact with the eyeball and causing pain, irritation and possible corneal abrasion. Collodion is prepared by dissolving pyroxylin or gun cotton in ether and alcohol. When applied to the skin it dries rapidly, forming an adherent glossy contractile film that contracts the underlying skin. This short communication describes the effectiveness of collodion, painted along the cutaneous margin of the eyelid, in reversing inversion of the lid by contracting the underlying skin. Cooper, who took a special interest in diseases of the eye, considered the collodion method of treating entropion to be original with himself:

Since the last meeting of the Society I have had an opportunity of fully testing the efficacy of Collodion as a remedial agent in Entropion, and though I am not aware of any other person having used it, to give testimony that would afford weight to my opinion, I feel perfectly at liberty to recommend it as an agent capable of superseding the necessity of a surgical operation in the cure of that disease.

Although collodion is no longer listed among the now more sophisticated methods of treating entropion, it may well have had a temporary palliative value in Cooper's day.

Appendix C. "A New Instrument for Cauterizing the Urethra"
By E. S. Cooper, M.D.

Urethral strictures in men caused by gonorrhea, a common problem in the pre-antimicrobial era, were dilated by catheters and curved metal probes of various sizes passed down the urethra. When dilatation failed because of denseness of the stricture, it was common practice to apply a caustic via catheter to the strictured area in order to soften the contracted tissue and facilitate its dilatation. In this communication, Cooper described an instrument of his own design for this purpose. The instrument had the shape of a common catheter but was made of copper and perforated with small holes at its distal end:

Its mode of application is as follows: Having it well oiled, it is introduced as far as the stricture; after which, a solution of nitric acid and water is poured into it, which, passing down the holes, throws out to the parts corresponding the nitrate of copper just formed by the union of the acid and the copper. The degree of cauterization will be graduated by the strength of the solution and the length of time it is permitted to remain.

Cooper designed several models of the copper instrument for different types of stricture and also shaped its mouth like a funnel more freely to receive the caustic. He recommended his invention as easy to fashion by coppersmiths and convenient to apply by physicians, "especially in places remote from the largest cities."

John Hunter (1728-1793) was the British surgeon who elevated surgery to the status of an experimental science. Both he and the eminent French venereologist Philippe Ricord (1799-1889) used such caustics as silver nitrate to relieve resistant strictures. Cooper's copper tube was designed to facilitate the accurate application of a caustic solution. Nowadays sophisticated instruments passed down the urethra accomplish the same task with knife, cautery or possibly laser when dilatations alone are ineffectual.[43][44]

Appendix D. "Incomplete Anchylosis of the Knee-joint"
By E. S. Cooper, M.D.

Cooper's third paper to the Society concerned the treatment of orthopedic deformity which, like diseases of the eye, was a field in which he sought to cultivate referrals and establish preeminence in the region. He reported the treatment of three patients, two men and a little girl, who had marked chronic flexure of the knee joint which retained only the slightest motion, indicating that the fixation or "anchylosis" of the joint was almost but not entirely complete. By an ingenious apparatus consisting of splints, springs, rods and a boot, custom-designed for each deformity, he enabled the patient to walk. When bearing weight on the foot, pressure was transmitted through the apparatus to extend the knee joint which gradually straightened until the patient could walk again without crutches.

It is in the process of cure by walking that I claim originality in the treatment of these cases. Though many cures have been effected by gradual extension alone, or by extension and forced motion, a plan not new to the profession by any means, but one that must appear imperfect to all who are familiar with this class of deformities; since in many, if not a majority of cases, where anchylosis has been of 10 or 12 years standing, the limb is too weak to bear the patient's weight, even though the motion of the true joint was unimpeded.

Cooper was indeed an early advocate of the beneficial effects of weight-bearing in the management of orthopedic conditions of the lower extremities, a principle that later gained general acceptance. It is of further interest to note that he was always anxious to have his patients observed by other practitioners who could substantiate his claim of good results. In the case of his first patient with anchylosis of the knee joint (who consulted him on 26 January 1852), "The progress of cure, and the principles of treatment were frequently noticed by Drs. John L. Hamilton, J.T. Steward, W.R. Hamilton, and L.C. Lane, of Peoria."

Appendix E. "Remarks on Transforming lacerated and Contused, into Incised Wounds" By L.C. Lane, M.D., of Peoria

Cooper read this paper at the meeting on behalf of Lane.

After stating the important principle that a wound associated with irregular laceration and heavy bruising heals poorly, Lane made the point that surgical excision of dead and badly damaged tissue leaves behind only viable normal structures capable of rapid healing. He then cited the case which led him to that conclusion - a 34 year old German bootmaker who on 31 December 1851 received a violent wound from the explosion of a gun in his hand, blowing away its palmar surface:

Dr. E.S. Cooper and myself were called to the case a few minutes after the receipt of the injury. After making a careful examination of the wound, as to its nature and extent, it was a matter of considerable demur with us whether nature would be sufficient to effect a cure without amputation of a part or all of the hand. . .

The idea immediately suggested itself to Dr. Cooper of trimming the wound, and thus changing its nature from a lacerated and contused to a neatly incised one - an idea novel in itself. . . Almost the entire surface of the wound was pared to a sufficient depth to remove the lacerated soft parts, leaving it for the most part one of smooth incision. . .

I shall not enter into a tedious detail of the after treatment . . but let it suffice to say that (healthy granulations sprang up and the wound healed kindly). This was satisfactory evidence to me that had not the worst and nearly all the surface been changed from a lacerated and contused to an incised wound, the patient would have lost his hand.

This rather elementary case report conveys two pertinent messages: Cooper was a gifted surgeon able to act intuitively on a basic surgical principle generations before its many applications were fully appreciated: and Lane was associated with him in practice in Peoria in December 1851.

Third Annual Meeting of Illinois State Medical Society
Chicago, Illinois, 7-9 June 1853

The Society met in the Common Council Chamber of the City of Chicago and, in the absence of President Rouse (from Peoria Medical Society), the meeting was called to order and its preliminary session conducted by First Vice President Thomas Hall (from the Stark County Medical Society). Pursuant to the recommendation of the Committee for Nomination of Officers, Professor Daniel Brainard of Chicago was elected President of the Society and took the chair as presiding officer for the remainder of the meeting.

Delegates from the Society to the next annual meeting of the A.M.A. to be held in St. Louis in May 1854 were elected and Thomas Hall of Toulon was among those chosen.

During the Society's administrative deliberations, Elias Cooper took no significant part but, as before, he contributed to the scientific program by reading a paper. His presentation on "Medical and Surgical Diseases of the Eye" was discussed by Drs. Hall and Brainard. Unfortunately, this paper was not reproduced with the Transactions as was the case with his previous contributions, and a search of the medical literature did not locate its publication elsewhere.

It was at this Chicago meeting of the State Society that Cooper's opponents, Drs. Arnold and Hall, planned to bring against him the charge of unethical practice and call for his expulsion because he "advertised" his hospital in the public press. We shall return shortly to this issue.

Seventh Annual Meeting of American Medical Association
St. Louis, Missouri, 2-4 May 1854

Elias Cooper attended the A.M.A. meeting in St. Louis as a Delegate from the Illinois State Medical Society. However, according to the Minutes for the 1853 meeting of the State Society, he was not among the delegates elected to represent the Society in St. Louis. Dr. Thomas Hall was elected by the Society as a delegate to the St. Louis Meeting of the A.M.A. but did not attend. The Minutes of the 1852 meeting of the State Society show that Cooper was elected to serve as a delegate from the Society to the A.M.A. at its New York meeting in May 1853 but, according to the A.M.A. Minutes, he was not present. These data are cited merely to clarify the record with respect to Cooper's attendance at meetings of the A.M.A. As far as we can determine, Cooper attended only one A.M.A. meeting - that held in St. Louis in May 1854.

Cooper's surgical teacher, Professor Charles Pope, Dean of the Medical Department of St. Louis University, was elected President of the A.M.A. at the St. Louis meeting and presided over the sessions. This must have been a pleasing development for Cooper who no doubt took the opportunity to renew his friendship with Dr. Pope, and to revisit the familiar environs of his alma mater, the St. Louis University. Perhaps it was in part to this congenial ambiance that Cooper owed the signal recognition he received during the meeting. He was elected Chairman of the Committee on Orthopedics of the A.M.A. with the responsibility to report on the status of the specialty in the United States at the next meeting. For a surgeon from Peoria, without the aura of a large metropolitan practice or an academic title, to be elected to such a chairmanship suggests a far more than local appreciation of his work.

Two months later, in order to gather information for his report on orthopedic surgery, Cooper wrote the following letter:[45]

Peoria, Ill, July 1st, 1854.

Dear Sir,
Having been appointed by the American Medical Association to report upon Orthopaedic Surgery, I take the liberty of addressing the medical men of this country generally, by circular, soliciting their aid in the fulfilling of that duty. The objects of the commission are to place within the reach of all practitioners the improvements that may now be in the hands of a few, and to obtain an accurate estimate of the condition and progress of Orthopaedia, in the broadest acceptation of the term, embracing statistics of treatment for removing obstructions in the movements of all Diarthrodial Articulations, either with or without dividing tendons, and endeavor to ascertain if there exists in America any cause for a vibration of the medical mind between an almost exclusive reliance upon tendon cutting, or the appliance of machinery to remove deformities, as has heretofore existed in most parts of Europe.

I wish to know the number of cases of Club-foot, Immobility of the Knee Joint, Permanent Contraction of the Jaws, Wry Neck, Curvature of the Spine, etc., etc., which have come within your observation, at your present residence, the number submitted to treatment, and the attendant success, as well as whose machinery was applied, etc., etc.

Respectfully yours,
E.S. Cooper, M.D.

The American Medical Association met for its Eighth Annual Meeting at Philadelphia, 1-4 May 1855. During the meeting there was a call for the Report on Orthopaedic Surgery by Dr. E.S. Cooper of Peoria. He was not present at the meeting and no report was submitted. He had left Peoria for the Pacific Coast the month before.

Fourth Annual Meeting of Illinois State Medical Society
Lasalle, Illinois, 6-7 June 1854

Dr. Cooper's participation in the routine business of the Society was minimal during this meeting The Minutes record no participation by him in any of the decisions. It is as though organizational issues and parliamentary maneuvering had lost their attraction for him. Perhaps in deference to his seniority in the Society, he was again elected as a delegate to the A.M.A. at its next meeting to be held at Philadelphia in May 1855.

As usual he contributed to the Society's scientific program. On this occasion he read a lengthy paper, published only in the Transactions, with the following wordy title: "Walking rendered the Primary Element in the Cure of Deformities of the Lower Extremities; its early Adaptation to White Swelling and Coxalgia, with Apparatus for carrying out the designs of the same."

This paper is essentially a defense and further documentation of the effectiveness of the apparatus and methods previously described in the paper on "Incomplete Anchylosis of the Knee Joint" which Cooper presented to the Society in 1852, and which was later criticized severely in the medical press. For example, the editors of the Western Medico-Chirurgical Journal, organ of the Iowa State Medical School in Keokuk (an institution not unknown to Cooper), sent him a copy of that periodical containing a review of the anchylosis paper which conceded the apparatus to be Cooper's invention, but considered it worthless. An editorial in the Philadelphia Medical News and Library claimed that Cooper's methods had already been in use for many years, but the editors never supplied any reference to prove their point. To which Cooper responded:

I have either greatly overrated my claims of originality (and) the value of my inventions or the editors of medical journals have done me a great injustice. I shall never give priority to any one who has not published previously to me in 1852, nor lose confidence in my methods because they are condemned by others.

Cooper's championing of progressive weight-bearing (walking) and joint mobilization, controlled by appropriate apparatus, and his insistence that these activities are essential to musculoskeletal development and restoration of function, find their counterpart in modern orthopedic practice - with the use of sophisticated "apparatus" that would have fascinated him. Current methods affirm basic principles he long ago espoused.

In one arena after another, Cooper was proving to be forward-looking, firm in his convictions, and self-assured in confronting his adversaries.

Fifth Annual Meeting of Illinois State Medical Society, Bloomington, Illinois, 5-6 June 1855

Cooper is not mentioned in the Minutes of the meeting. His name does not appear on the List of Members of the Society published in the Transactions - nor do the names of John D. Arnold and Thomas Hall. Cooper had arrived in San Francisco on 26 May 1855.

A Question of Ethics

When Cooper printed notices in regional newspapers in the fall of 1851 describing the services available in his Peoria Infirmary, he embarked on troubled waters. The recently founded American Medical Association made strict adherence to its Code of Ethics a condition of legitimacy for physicians and medical organizations alike. The Peoria County and Illinois State Medical Societies adopted the Code which, among other restrictions, proscribed advertising. It was the responsibility of the Societies to interpret and enforce this ruling which they proceeded to do. Certain influential members of the Societies claimed that Cooper's newspaper notices regarding his Infirmary were "advertising;" that they were therefore unethical; and that he should be censured.

Cooper's dispute with the Peoria and the Illinois State Medical Societies over his newspaper notices was so complex and lengthy that we have deferred discussion of it until now when we have completed our summary of the founding and early meetings of these two organizations.

The first phase of the convoluted process that eventually ensnared Cooper began in June 1851 at the First Annual Meeting of the Illinois Medical Society. This meeting was about six months prior to Cooper's wide publication in regional newspapers of notices regarding his Infirmary. During the meeting a Resolution was introduced before the State Society to the effect that the time had come when the people of the State of Illinois ought to regulate, by statutory enactment, the qualifications of those who practice medicine and surgery (i.e., require that every practitioner have a bona fide MD degree). In addition, the Resolution enjoined the Society to take any other necessary steps (these would include suppression of advertising) to protect the good name of the profession:[46]

Dr. Thomas Hall of Toulon was a member of the committee of three elected to implement the Resolution. As a result of his membership on the committee, Dr. Hall shared with the other two members the role of guardians of ethical standards for the Society, a responsibility he took very seriously - as one might expect from his background that he would.

It was a year later, at the June 1852 meeting of the Illinois State Medical Society, that the following incident occurred relevant to the Infirmary notices Cooper had then been publishing for the previous 9 months.

By an unfortunate coincidence, Dr. J.W. Halsted, an Oculist in neighboring Stark County, was carrying out a newspaper campaign of his own simultaneous with that of Cooper. This is Halsted's notice:[47]

Dr. J. W. Halsted, Oculist

Residing at La Fayette, Stark County, Illinois, would respectfully announce to those afflicted with diseased eyes, whether of recent or long standing, that he is fully prepared to treat all such cases with the utmost care and attention. From his knowledge and success in the treatment of diseased eyes, he feels confident in thus offering himself to the public. He would further state for the benefit of those who may reside at a distance wishing to put themselves under his care, that he has provided suitable boarding accommodations where all such persons will be provided for in the best possible manner, and that no means will be spared to insure entire success.

Dr. Hall, who was the delegate of the Stark County Medical Society to the 1852 meeting of the State Society, called the State Society's attention to Halsted's notice, which was in some respects similar to the notice that Cooper was running in newspapers at the same time. Hall reported to the State Society that the Stark County Society found Halsted's notice to be a form of advertising and offensive to ethical practice. The Society demanded that he withdraw it. When he refused to do so, Halsted was expelled from the Stark County Medical Society which now wished the opinion of the State Society on the propriety of the action they had taken. After considerable discussion, the members of the State Society voted that "such advertisement is a sufficient ground for expulsion," and adopted the following resolution:

Resolved, That (Dr. Halsted's) advertisement, presented for the consideration of this Society by Dr. Hall, is unprofessional in its character, and contrary to the code of ethics of this Society.

Thus the ground was laid and the precedent established for a move to expel Cooper from the State Society for running a similar ad. What back-stage maneuvers took place at the State Society meeting in 1852 to censure Cooper, or to begin recruiting a consensus for such action, we do not know. However, later events suggest that the Halsted expulsion was a dress rehearsal for an attack on Cooper.

Cooper was aware of the implications for him of the action taken in the Halsted case; but he did not anticipate the circumstances under which open hostilities would break out. When the attack upon him came a year later on his home ground in Peoria, it took him by surprise. The circumstances were as follows. The Peoria County Medical Society met on 1 June 1853 in the office of Dr. Hamilton to transact routine business, including the election of delegates to the forthcoming meeting of the State Society to be held at Chicago 7-9 June 1853. The Minutes of the Peoria Society provide the following account:[48]

Peoria, 1 June 1853

The society then proceeded to the election of delegates to the state medical society. Dr. (John D.) Arnold was nominated and elected by a vote of 5 to 2. Dr. Cooper (was then) nominated. Dr. Arnold objected to the nomination on the grounds of alleged quack advertisement. After a long discussion Dr. Cooper withdrew has name as a candidate. Dr. Stewart then moved a reconsideration of the vote taken on Dr. Arnold's election and presented certain charges of unprofessional conduct against him. A discussion ensued but it growing very late, the society adjourned till tomorrow evening at same place.

Peoria, 2 June 1853

The society met pursuant to adjournment, president in the chair. Discussion concerning Dr. Arnold's case continued. At a late hour he resigned his delegation. The following preamble and resolution (were) then offered by Dr. Dickinson and passed.

Whereas a variety of breaches of professional etiquette have been charged against Dr. J. D. Arnold by various members of this Society some of which perhaps have been proved to the satisfaction of a majority of the gentlemen present, but in consideration of Dr. Arnold having expressed his regret at such breaches of etiquette and his determination that nothing of the kind shall occur in the future, therefore

Resolved that no further action be taken. . .

Dr. Hamilton, Sr., then offered the following resolutions which were passed:

Whereas the conduct of Dr. E. S. Cooper in advertising his eye infirmary and orthopaedic Institution in a very unprofessional manner has rendered himself obnoxious to the unqualified censure of the Society, therefore

Resolved that we do hereby express our entire disapprobation of the course pursued by him in this respect, and

Resolved that in consideration of the doctor's expressed readiness to conform to the opinion of the Society regarding this matter and in view of his perfectly honorable and dignified course otherwise, it is but due to him to overlook all past offences in view of his promise to offend no more, and

Resolved that a copy of these resolutions be sent to the State Medical Society.

When Cooper departed for the June 1853 meeting of the State Medical Society in Chicago, he was under the impression that his arraignment and acquittal before the Peoria Society only a few days previously had settled the advertising issue. In this assumption, he was sadly mistaken for he underestimated the vindictiveness of the clique determined to discredit and humiliate him.

Cooper was no stranger to conflict over his professional activities in Peoria where he had already faced down strident critics of his dissecting. But the coming challenge was far more serious for it threatened to undermine his professional "honor." The success of his Infirmary and surgical practice; his intense competitiveness tinged with a certain arrogance of opinion; and his flouting of conventional ethics by running newspaper notices regarding his Infirmary had provoked a malignant combination of jealousy and self-righteous zeal among a few of his erstwhile colleagues. He was soon to be introduced at the State level to the fratricidal infighting for which the medical profession of the day was notorious.

At this point we must call special attention to the fact that the Minutes of the June 1853 meeting of the State Medical Society do not so much as mention that charges of unethical behavior (advertising) were brought against Cooper during the meeting. Lack of record on this subject is not surprising since such information was commonly not included in medical society minutes unless some action was taken - and we assume that there was no formal indictment of Cooper's behavior by the State Society. Thus we have only Cooper's word that an attempt was made during the June 1853 meeting to expel him from the Society.

His version of the incident is detailed in the following lengthy and caustic letter to the President and Members of the State Society for consideration by the Society at its Fourth Annual Meeting to be held at Lasalle 6-7 June 1854. The letter reveals a determined and self-assured man (he was thirty-three), independent in thought, unafraid of controversy, and formidable in polemic. He claimed the right to inform the public directly about his Infirmary, based on the important specialized services it made available to the region; and he rejected the authority of a medical society to deny him that right.

The following letter from Cooper to the President and Members of Illinois State Medical Society, long and rambling though it may be, merits recording here in full for it reveals in Cooper's own emotional words his concept of specialization, the vexing realities of small-town specialty practice, and a combativeness to which we shall become more accustomed as we follow his career.[49]

Peoria, Illinois
Early 1854

Mr. President and Gentlemen (of the Illinois State Medical Society),
I am charged of non-professional conduct in advertising my Eye Infirmary and Orthopedic Institute of Peoria.

Before attempting to commence my own vindication in the affair permit me to say that I have always designed to let my course in this respect be shaped by the opinions of the profession. I would at first almost as soon have given up my Institution as to have had my course condemned by a respectable number of reputable physicians since nearly all the reputation I have acquired has been through my professional brotherhood. My plan was to pursue a course that could not be objected to by the most fastidious in orthodoxy.

That I had a right to announce my Institution I judged it but reasonable to suppose from the fact that all public institutions do the same. . .

There are hundreds of cases requiring the precise treatment that can be given at an institution prepared for the purpose and which could not be treated advantageously in another place. These patients are not being treated at all or are in the hands of the unskillful, such practitioners as take no medical journal, and consequently there is no means of reaching them but by circular. The very class of cases in fact that would benefit most from my institution are such as would hear of me last. A code of ethics therefore which curtails the sphere of usefulness of anyone is of doubtful propriety and should never be followed by those whose privileges are unjustly trampled upon. (Emphasis added.)

If the code of medical ethics of the State and of the National Medical Association is intended to imply that I shall not pursue whatever department of the profession I wish; and that I shall not have a private hospital in which to carry out my treatment; and that I shall not make the same known in any way best calculated to be most creditable to myself and beneficial to the community - all I have to say is that the code may go to thunder and so may those who thus construe it.

I have expended nearly five thousand dollars in preparing buildings, bedding and other appurtenances of a private hospital. I have devoted almost four years to private study and dissections which I might have devoted to the more lucrative employment of general practice. This sacrifice of time and money I made the better to qualify myself for the treatment of deformities for which I ever had a predilection. I have not lost sight of the many sacrifices thus made on account of my profession nor am I going to forget that my profession shall repay me. I have not forgotten the popular fury and the criminal prosecutions I had to defend myself against when, had I not been dissecting, I might have pursued the even tenor of my professional career, making money and friends where I was losing money and making enemies.

Who would be so unreasonable as to propose that in the opening of my institution after engaging a matron and nurses in advance, buying buildings which I could appropriate to no other purpose, that I should have had permission from the Illinois State Medical Society merely to insert my name in the Peoria papers as E.S. Cooper, M.D., Physician and Surgeon, without the privilege of making the slightest allusion to my institution or its designs, which would be the case if I am not permitted to advertise for the treatment of peculiar diseases.

If it is wrong for an individual to pursue a specialty, why should Philippe Ricord, famous French venereologist, be encouraged in Paris at the head of a venereal hospital or Doctor G. . . , at the head of an orthopedic institution, both of whom are distinguished medical men. In fact, we cannot look around us in want of examples in which individuals have had private hospitals for the treatment of special diseases. Only a few years ago Valentine Mott of New York (to whom we shall refer again later) opened an Orthopedic Institution and sent circulars all over the United States announcing the same. Such men have a decided fondness for the instigation of particular branches of the profession and the history of medicine in all ages proves that it is to these persons we owe our greatest improvements in both medicine and surgery because special devotion gives special proficiency.

Any Institution therefore that discourages the cultivation of particular parts of the profession should be condemned as obnoxious to improvement and incompatible with its interest; and an association does discourage such effort if it cuts off the only means by which an individual can make himself known to a certain portion of the population with which it is his interest to deal. Those physicians whose wish it is to practice medicine, generally feel very independent in regard to advertising when they know full well that the entire community in which they reside must soon hear of them by their own doings, and that they can immediately be appreciated according to their merits. But the case is very different with the practitioner who wishes to extend his practice only to one or two classes of cases in which if all that ever occur in his vicinity should fall under his treatment he would have but an inadequate business.

Another apology for my past course is that some practitioners are so illiberal as to endeavor to prevent patients going off to be treated but, in preference, abandon them to nature although perhaps readily treatable by those whose special province is to treat such.

For many months Dr. Thomas Hall, who has been a leader in bringing this charge against me for advertising my institution, kept a patient from coming to me who could neither walk nor even stand alone and whom he had long before abandoned as incurable or only curable by the process of nature, a process somewhat tedious to an individual who could not get one rod from his door for nearly three years without being carried. This patient was Charles Rood of Osceola, Stark County, Illinois. He stood alone on the fourth day after his admission into my institution and in 10 days walked 150 yards.

Dr. Arnold of Peoria, another leader in bringing the charge against me, kept a patient from coming to me long after he had abandoned the case to nature. This was Fenton Shipler who had been unable to stand alone for 12 months when he placed himself under my treatment, but who began to walk in a few days and to walk well in a few weeks.

I will have to confess that it looks unfair to bring up, in a controversy like this, cases occurring in private practice; but I am fully convinced that whatever errors I may have committed, the present complaint has originated alone among my enemies who have either ulterior motives or are prejudiced against me.

Let us take a retrospective glance and view this matter of opposition to my course from its origin. It assumes the appearance of a conspiracy under the influence of Drs. Arnold and Andrew of Peoria and Dr. Hall of Toulon. At the Second Annual Meeting of the Illinois State Medical Society held in Jacksonville in June 1852, Dr. Hall secretly agitated the affair by showing copies of my advertisement to different members of the Society after having conferred with Dr. Arnold in Peoria in regard to it. The encouragement to proceed openly at that time was not so flattering as to justify his trying it. However, when Dr. Hall returned to Peoria he tried to soothe his coagitator, Dr. Arnold, by stating that he thought I would slacken my will after that. This is Arnold's statement subsequently made before the Peoria City Medical Society in June 1853.

Between the meeting of the State Society in June 1852 and the meeting of the Peoria Society in June 1853, it was a common observation among the profession of Peoria that Drs. Hall and Arnold were arranging their plans for a systematic attack on me, and that Dr. Quigley of Pekin was likely to be added to the list of my accusers. On 1 June 1853, immediately before the Third Annual Meeting of the State Society in Chicago on 7 June 1853, Dr. Arnold introduced a charge against me before the Peoria City Medical Society for advertising my institution and read at the same time a letter from Dr. W.C. Quigley very abusive to myself.

This created a discussion in which all the members expressed their opinions freely. As my friends concurred in expressing the opinion that it was against the code of ethics to advertise for the treatment of special diseases, I agreed to be guided by the verdict of the members of that body and promised to advertise no more; to issue no more annual reports of my institution; and not to do anything that would publicly identify myself with any particular branch of the profession. In return, I should have permission to keep open my institution for the reception of patients in a perfectly normal way. To this agreement on my part I have adhered ever since. I agreed to this willingly because it appeared to be the wish of a majority of the members that I should do so. In fact, I personally drew up the resolution in which my mode of advertisement was pronounced censurable by the Peoria Society. I did this because I preferred suffering myself to having the harmony of the Society marred in the slightest on my account. But in what manner have my accusers replied?

Dr. Arnold concurred in the vote on the resolution by which my past course was condemned, and also in the vote by which I was exonerated from all blame in consideration of my expressed willingness to be guided by the opinions of the Society as soon as I had ascertained what those opinions were. Therefore, as far as the Peoria Society or any of its members were concerned the matter was of right put to rest unless necessarily revived by some subsequent delinquency on my part. But instead of acting as any gentleman of honorable principles would have acted, we find Arnold going immediately to the meeting of the State Medical Society on 7 June 1853 in Chicago with the plain object of agitating the matter there. This he did although freshly from the scene of his own disgrace before the Peoria Society where he was judged to have violated every high-toned principle of a professional gentleman by traducing the character of his professional brethren by false statements; by stopping messengers on their way to the prescription shops from the sick room of other physicians' patients; by examining the prescriptions and making remarks about them; and by making it an established custom to visit other physicians' patients without being called - behavior which a practitioner possessing a spark of honor would avoid as he would a loathsome thing. . .

Let me examine still further the course pursued by my enemies. Dr. Quigley, formerly of Pekin now of Chicago, is one of them and his conduct will compare favorably with that of Arnold. Not knowing how else to vent his spleen, and like Dr. Chambers (of Peoria) being anxious to do something, Quigley collected the medical men of Pekin together such as he could get to join him, and formed a Society of which he became president. A Delegate from Pekin was then appointed to the State Medical Society whose duty it was to bring forward this same affair with the view of having me expelled. What became of the delegate, I never heard.

This Pekin Medical Society of which Dr. Quigley was the President consisted of Drs. I and W. Mans, both of whom were druggists and industrious vendors of nostrums; Dr. Wright, a sort of one-horse druggist who kept hardly anything but patent nostrums and sold one of his own for ague called Wright's pill; and Dr. Hinsey, who is an avowed eclectic and advertises himself as such. Drs. Fitch, Roberts and Merrik, regular physicians, refused to have any connection with the Pekin Society at the time.

Dr. Elwood Andrew of Peoria, another of the clique, has been ignominiously expelled from the Masonic order for gross violations of morality and decency.

So it will be discovered that it is to those men generally, whose own course is justly obnoxious to censure, that I owe most of this opposition. Take the mote out of thine own eye and then see clearly that which is in thy brother's.

I have dealt in personalities to an extent scarcely justifiable were it not for the fact that the charge brought against me before the meeting of the State Medical Society at Chicago in June 1853 was the result of personal ill feeling alone. I know this to be the fact. Though Dr. Chambers came forth and appeared the champion of the cause, it is very easy to perceive that he is merely a tool of Arnold. . . . Whatever wrong I had committed had been atoned for to the Peoria City Medical Society if no subsequent cause of complaint should occur. All that I promised to the Peoria City Medical Society in June 1853 I would have been promised the year before in June 1852 to the State Medical Society had a single unprejudiced member expressed a desire to have it so because, as I said before, my desire was to pursue a course that could not be objected to. It was at the meeting of the State Society in Jacksonville in June 1852 that Dr. Hall tried initially to thrust me into the notice of the Society on the shoulders of one Dr. Halsted but, as Dr. Halsted had no institution to advertise, there could be no analogy between our advertisements.

In conclusion, I would state that whatever wrongs I have committed have certainly been committed under a very fair semblance of being right; that whether it is compatible with the dignity of the profession to follow special departments of Medicine and Surgery, I have the most illustrious examples set before me of those whose course I would be proud to pursue and whose expectation I would be proud to assimilate even in the slightest. . . . I have always said that I am willing to have my course in regard to the publicity of my institution guided by the views of the profession. . . . I feel no desire to violate my obligations to the Peoria City Medical Society made last year in June 1853, however unnecessarily binding these may have been because my friends there wished them so. Therefore, I consider that I have nothing more to do, that I have no concessions to make to those who brought up this charge to the State Society because it originated among my enemies who do not seek the good of the Society so much as they seek to injure me.

The active agent is Dr. Arnold who cares naught about the State Society unless to further his plans as his former course proves. He never left home to attend State Society meetings though to each he was made a delegate from the Peoria Society until the State Society meeting in June 1853 when his dishonorable conduct prevented his appointment as a delegate from the Peoria Society though there was a vacancy, and he expressed a wish to be appointed which was denied. He was determined to go anyhow, which he accordingly did. Who can doubt his object in attending the State Society under the circumstances?

Dr. Hall, who works with Arnold in this affair, has a motive very different from his. Dr. Hall is honest but prejudiced; and while Dr. Arnold wants to injure me in order to advance his own interests, Dr. Hall wants to injure me for the benefit of the Society. While one would wrong me by being unjust himself, the other would wrong me from being biased by prejudice. It is from these wrongs that I claim exemption of this Society. I claim it in full confidence because I have a right to claim it.

Here ends the controversy over Cooper's advertising of his Peoria hospital, as far as we can determine from existing records. In the absence of evidence that the State Medical Society took any action in the matter during either its June 1853 or its June 1854 meeting, we can assume that Cooper's cogent arguments and his vow to desist from further advertising were persuasive and led to a dropping of the complaint. Whether he learned from this experience that future advertising would likely again expose him to the censure of his medical colleagues is an interesting question. In the light of similar charges against him during the California phase of his career, we might be tempted to believe that the Peoria lesson was lost on him. On second thought, it seems more likely that the keenly perceptive and strong-willed Cooper simply meant it when he said:

. . . if the code of medical ethics . . .is intended to imply that I shall not pursue whatever department of the profession I wish; and that I shall not have a private hospital the latter to carry out my treatment; and that I shall not make the same known in any way best calculated to be most creditable to myself and beneficial to the community - all I have to say is that the code may go to thunder and so may those who thus construe it.

This Manifesto and defiant challenge of the established order has about it the ring of conviction and an uncanny prescience. Cooper was simply ahead of his time, as is clearly evident in these excerpts from the A.M.A. Code of Ethics, as interpreted in 1989 by its Council on Ethical and Judicial Affairs:[50]

A.M.A. Code of Ethics on Advertising, 1989

There are no restrictions on advertising by physicians except those that can be specifically justified to protect the public from deceptive practices. A physician may publicize himself as a physician through any commercial publicity or other form of public communication (including any newspaper, magazine, telephone directory, radio, television, direct mail or other advertising) provided that the communication shall not be misleading because of the omission of necessary material information, shall not contain any false or misleading statement or shall not otherwise operate to deceive. . .

Objective claims regarding experience, competence and the quality of the physician's services may be made if they are factually supportable. Similarly generalized statements of satisfaction with a physician's services may be made if they are representative of the experiences of that physician's patients. . . .

Statements that a physician has an exclusive or unique skill or remedy in a particular geographic area, if true,. . . are permissible. . . .

Cooper would have had no difficulty operating within modern guidelines. Today's ethical codes allow publication, freely through all media, of advertisements and other releases by physicians, hospitals and health service organizations provided they are not deceptive or contain false, misleading or confidential information.

Cooper in Europe

The enterprising spirit, moral courage, stubborn individualism and surgical talent that Cooper demonstrated during his Peoria years were attributes that fitted him uniquely for his California venture. By the time he left Peoria he was a hardened veteran of professional competition and intrigue. In consequence, when he arrived in San Francisco in May 1855, he was prepared to embark with scarcely a day's delay upon the vigorous execution of his plan to found a medical school.

As we have seen, Cooper's plan had been quietly germinating throughout his sojourn in Peoria. By mid 1854 he was ready to carry out its first phase comprised of visits to medical centers in Britain and France - a pilgrimage that would not only expand his knowledge of medical education and surgery, but also enhance his stature in the profession.

Our first indication of his planned departure for Europe is found in four letters written by the highly respected Nathan S. Davis, MD, Founder of the A.M.A., Professor at Rush Medical College and Editor of the North-Western Medical and Surgical Journal. These letters, dated 1 and 21 September 1854, were addressed to prominent surgeons at the College of Physicians and Surgeons in New York and at New York Hospital. Davis's message to each of these surgeons was substantially as follows: "I write to introduce my friend, Dr. Cooper of Peoria, who will be traveling to Europe and wishes to stop over in New York for a few days to observe your work." This would be Cooper's first journey east of the Alleghenies.[51]

We have already referred to his transatlantic voyage on the Arabia from New York to Liverpool 4-14 October 1854. The only reliable information we have about Cooper's itinerary in Europe is found in the Diary of his younger brother Jacob who was at Edinburgh when Elias arrived in Britain. On 18 October Elias joined Jacob in Edinburgh for a joyous reunion. After three days in Edinburgh, Elias went down to London on 21 October where he spent nine days making contacts with eminent surgeons before crossing the Channel to Paris on 30 October. While in Paris, Elias became ill with "dyspepsia" which was of such concern to the tenderhearted Jacob that he went to Paris on 22 November to be with his ailing brother. A few days after Jacob's arrival in Paris, Elias received word from Peoria that his presence there was much needed to look after his business affairs. Although Jacob had planned to remain longer in Europe, Elias much desired his company on the voyage home and Jacob agreed. Thus Elias, after a month in Paris that was marred by persistent abdominal complaints, departed with Jacob for London on 30 November. During their stay in London from 1 to 7 December, Elias felt so much better that he again visited hospitals and principal medical gentlemen. Meanwhile Jacob went sightseeing until December 7th when he made the following entry in his Diary: "This day completed my twenty-fourth year! I can scarcely believe I am so old for I have done so little. . . Left London at 7 A. M. on the . . . Parliamentary train bound for Liverpool. The distance 200 miles. Arrived in Liverpool at 8 P.M." On December 9th he and Elias embarked on the S. S. America, a Cunard steamer bound for Boston where they arrived on 25 December 1854.[52]

During his European interlude of 57 days from October 14th to December 9th, 1954, Elias while in Edinburgh attended the Clinics of Symes and Miller. In Paris he observed the methods of Velpeau, Jobert, Nelaton and Ricord. The dexterity of the French surgeons impressed him, but he found deficiencies in their pre and postoperative care which in his view contributed to their less than optimum results. In London, he visited the surgical services of Fergusson and Erichsen. Even brief exposure to the practice of internationally recognized surgical authorities and the surroundings in which they worked would be of significant benefit to a keen observer like Elias who was already familiar with their contributions to the medical literature.[53][54]

The America docked at 10:30 A. M. on Christmas Day and at 1:30 P. M. Elias and Jacob were southbound on the Boston and New York Railroad. They changed trains in New York and headed west, arriving at the Cooper farm outside Somerville on 30 December 1854. On 9 January 1855 Elias took the train to Peoria, there to dispose of his hospital, close out his practice and prepare for the journey to California.

Cooper Invites Dr. Saul G. Armor to Accompany Him to California

Dr. Armor, born in Pennsylvania in 1819, was Cooper's contemporary. He received his MD degree in 1844 from Missouri Medical College where he was a pupil of the controversial Joseph McDowell. In 1849 he became Professor of Physiology, Pathology and Jurisprudence in the Medical Department of the University of Iowa at Keokuk. When Cooper was offered the professorship of Anatomy at Keokuk in 1851, Professors Armor and Hudson had the delicate task of withdrawing the offer because of an administrative technicality, as we have already related. Neither Armor nor Cooper was likely to forget that unpleasant incident.

In 1853 Armor won the prize offered by the State Medical Society of Ohio for the best paper on the subject: "Zymotic Theory of the Essential Fevers." This brought him to the attention of the trustees of the Medical College of Ohio who offered him the chair of Physiology and Pathology, which he accepted. This is how Armor chanced to be located in Cincinnati when Cooper returned from Europe and called on him there to discuss their joining forces and migrating together to San Francisco.

After their meeting in Cincinnati, there was the following exchange of letters.[55]

From Dr. Armor to Cooper:
Cincinnati, 28 January 1855

My dear Doctor:
Since my interview with you - and indeed for some time before - I have been strongly thinking of making a tour to the Pacific, and it is barely possible that I may conclude to go the coming Spring, after the close of our Session.

Are you making your calculations to (go) early in the Spring? At what time (will you) start, and what route will you take? Please write me on receipt of my letter. I have a brother - an only one - who recently talks of making his future home in California, and his decision may very much influence me as to my future.

It does appear to me to be a very desirable field for energetic young men; but, above all, I think I should like the climate.

Very truly yours,
Saul G. Armor

To which Cooper promptly replied:

Peoria, Ills., 9 Feb 1855

Dear Doctor:
My plan of operation in San Francisco is this, viz., in connection with the private (medical) teaching of which I mentioned at our interview in Cincinnati. My design is to engage in active practice as soon as possible and, by economy, endeavor to make considerable instruments in real estate which must rise in value in San Francisco to an extent almost unprecedented. With this for a foundation I should be led to hope in a few years to possess not only the wealth but likewise the reputation to enable me to establish a medical college.

That San Francisco is destined to make one of the largest cities on this continent - perhaps in the world - wants but a glance at her position to decide. There is China with a population of 360 millions and materials of exportation equal to that of 1/3 of the entire commercial world besides; and San Francisco will be her chief place henceforth as can reasonably enough be inferred from what has occurred already. This of itself would make it a great city to say nothing of the trade with Sister States and the balance of the world, and the impulse given by the construction of the Pacific Railroad which no one doubts will be speedily accomplished.

Now, Sir, you are young, have talents, ambition and abiding faith in being adequate to accomplish an important destiny in life, and as our tastes leading us to pursue different branches of the profession would not only remove all difficulties in the way of permanent harmony, but we might be immensely advantageous to each other from the commencement of our career, more particularly as we should have the prudence to keep our mutual understanding and plans a matter of secrecy.

I design leaving here for San Francisco about the last of May or the first of June (1855) but cannot affix a definite time at present as I have some real estate to dispose of yet and business to settle - making it a point to hold on to a bird in the hand.

I have given you my plans without reserve and shall be pleased . . .

(The letter ends here abruptly at the bottom of a page, and all the rest has been lost.)

What a dazzling prospect with which to tempt an adventuresome spirit, but it did not attract the hesitant Armor for whom California's greatest appeal was its climate. It was fortunate for him that he did not join Cooper who, above all, saw California as the land of the future where great deeds were possible for those with an abiding faith in their destiny. Had Armor teamed with Cooper, he would have found himself in harness with a tiger. Better for his peace of mind that he should spend the rest of his days gliding from professorship to professorship in established medical schools in the East, which he did - joining the faculty of Missouri Medical College in 1858, moving to the University of Michigan in 1863, and finally to Long Island Medical College in Brooklyn in 1866 where he became Dean in 1868. He continued on the Long Island faculty until his death in 1885.[56]

Better, also, for Cooper that he should travel alone to California. His searing ambition and contemptuous disregard for the sensibilities of San Francisco's self-anointed medical elite would have strained relations with any partner except his devoted nephew, Levi Cooper Lane, whom Providence later sent at a crucial juncture to sustain him.

By early April 1855 Cooper had concluded his business affairs in Peoria and terminated his practice. Jacob, who was visiting Esaias in Henderson at the time, came over to Peoria by stagecoach on April 17th and was delighted to find Elias looking very well - indeed, he "never saw him better." But when Elias told him that he was on the eve of departing for San Francisco, Jacob was greatly distressed. On April 19th the sad and trying hour of their separation came and Jacob accompanied Elias to the railroad station. "I went with him into the car and there took my long - I greatly fear my last - farewell." Elias set out for New York quietly, leaving Peoria without even giving notice to friends, one of whom later wrote of his disappointment in finding Cooper no longer among them.

When Jacob returned to Somerville on May 10th he received news that must have eased his sadness over his brother's departure for the West. Awaiting him was a letter from Centre College in Danville, Kentucky, announcing his appointment as Professor of Greek in the College. Now that he had a good situation that would enable him to support a family, there was nothing in the way of his marriage to Caroline. They were wed on 31 May 1855.

To California by Sea via Nicaragua

On about 23 April 1855, Elias left New York on a steamer that carried him down the Atlantic Coast to Central America on the first stage of his journey to San Francisco. He chose the route that involved crossing the Isthmus through Nicaragua.

The discovery of gold in California on the American River in 1848 created the Gold Rush of 1849 and a massive wave of migration that Cooper now joined. There were three possible routes from the East to the Pacific Coast - by wagon train across the western plains and mountains; by sea around Cape Horn; and by sea to a crossing in Central America and thence again by sea to San Francisco. The route by way of Central American was the most rapid and convenient of the three, being the itinerary followed by an increasing proportion of passengers, mail and treasure from the gold fields. Until completion of the transcontinental railroad in 1869, the Central American route remained the preferred way for the ordinary person or message to travel between the Atlantic and Pacific Coasts.

At the time of Cooper's journey, Central America could be crossed either through Panama or Nicaragua. The southern crossing at the Isthmus of Panama was the shortest. The distance between the Atlantic and Pacific Oceans was only 47 miles, with less than 300 feet elevation at the highest point. Nevertheless the hardships and perils of crossing the Isthmus through malarious tropical swamps and rain forest by mule-back and shallow-draft boat made this route at first relatively unattractive. This changed when on 27 January 1855, after heroic exertions, the last track was laid on the Panama Railroad, and on the following day a locomotive passed over it from ocean to ocean. From that time forward, it was possible to cross the Isthmus in half a day in the comfort of a railroad car. This assured that the Panama crossing would eventually become more popular than the northern option through Nicaragua. Sixty years later the Panama Canal was excavated along the same route as the Panama Railroad. On 15 August 1914 the Canal was opened by the United States to the commercial vessels of all nations. Not only was the Canal the greatest construction project the world had ever seen, the practical eradication of malaria and yellow fever in Panama by controlling the mosquito vectors during building the canal was one of the greatest triumphs of sanitation in history.[57][58]

Cooper chose to book passage on a shipping line that used the northern route. He landed in Nicaragua at San Juan del Norte on the Atlantic Coast then traveled by boat up the San Juan River and across Lake Nicaragua to its far shore, beyond which there was an overland trek of only 18 miles to San Juan del Sur on the Pacific Coast. Although the distance between oceans at Nicaragua was 174 miles as compared with 47 miles at Panama, all but 18 miles of the Nicaragua passage could be covered by boat. Also the higher latitude of Nicaragua was thought to make the climate cooler and tropical fevers less prevalent. The most obvious advantage of the Nicaragua route lay in its shorter over-all distance. The journey from New York to San Francisco via Panama was 5,245 miles; whereas it was only 4,871 by way of Nicaragua, a difference of 374 miles in favor of the northern crossing. This small advantage, however, was later more than offset by the convenience of rapid rail transit across Panama when that service became well established.[59]

Competition between shipping lines carrying traffic on a fortnightly basis between New York and San Francisco was fierce, Bankruptcies, mergers and rate-wars were frequent. Passenger volume on the Panama and Nicaragua routes was closely watched. In 1855, 15,000 passengers traversed Panama and 11,000 crossed by way of Nicaragua. Fares fluctuated erratically according to the state of hostilities among the carriers so we are unable to determine with certainty what it cost Cooper to travel from New York to San Francisco. We do know that in June 1854 steamers via Nicaragua charged $ 225 for first cabin accommodations, $130 for second cabin and $ 75 in steerage. At that time the trip from New York to San Francisco required approximately 33 days (11 on the Atlantic and 22 on the Pacific leg).[60]

On 4 May 1855 Cooper boarded the S. S. Sierra Nevada at San Juan del Sur on the Pacific. After 22 days at sea, steaming north off the Mexican and California coasts, his ship docked at San Francisco on Saturday, May 26th.

The "Captain Jim Story"

Cooper had the happy faculty of making interesting friends while on sea voyages. We have previously referred to his correspondence with the Honorable Hugh Keenan, U.S. Consul to Cork, Ireland, whom he met aboard the S.S. Arabia when on his way to Europe in October of 1854. He had a similarly pleasant experience in May of 1855 on the S. S. Sierra Nevada where he encountered a congenial fellow passenger named Captain James M. McDonald whose friendship and generosity continued throughout Cooper's life, and beyond. As sometimes occurs when facts are few and memories dim, an intriguing myth arose that attributed to Captain McDonald a decisive influence on Cooper's career. Stanford's Professor Rixford, a principal biographer of Cooper, wrote the following:[61][62]

Dr. Cooper greatly admired (Daniel) Brainard, founder of Rush Medical College, and conceived the ambition of emulating him and founding a medical college on the Pacific Coast. He sailed for Portland, Oregon, but on the steamer met one Captain James M. McDonald who prevailed upon him to leave the ship at San Francisco. I mention "Captain Jim" as we afterward called him because, out of this friendship for Doctor Cooper and thirty years after Cooper's death, he gave to Cooper College the (two varas of) land on which Lane Hospital (was erected), as well as ($ 25,000 in money for college purposes).

Professor Rixford did extensive research on Cooper's life, but the Rixford papers contain no hint of the origin of the "Captain Jim" legend. It is possible that Cooper himself was inadvertently responsible for the birth of this romantic fiction regarding his decision to settle in San Francisco. We have seen from his letters to Keenan and Armor that he was secretive about his plan to found a medical school in the city by the Golden Gate. Obviously these letters never came to Professor Rixford's attention. We assume that it was Cooper's reticence to speak openly of his seemingly quixotic plan to found a medical school in San Francisco that led to the poetic conception that he was bound for Oregon and that Providence in the person of Captain Jim influenced his fateful decision to disembark at San Francisco. We know that the Captain was a great admirer of Cooper, lent him money on very favorable terms, and was later a generous donor to Cooper Medical College.[63]

In any case, the entire sequence of events somehow led to the fanciful "Captain Jim Story" that was reported in good faith by Professor Rixford. Under the circumstances, those who prefer to believe the appealing notion that it was Captain Jim who convinced Cooper to remain in San Francisco should feel free to do so - but should keep in mind that the now available evidence indicates that Cooper had long before made up his mind on his destination.

Intimations of Mortality

When Cooper visited Europe he was just 34 years of age but was already beset with early symptoms of the strange neurological and gastrointestinal disorder which was to bring his tempestuous career to a close in just 8 more years. Levi Cooper Lane made the following reference to the onset of Cooper's chronic and ultimately fatal disease in the Obituary he wrote in 1862:[64]

In 1854, (Cooper) visited Europe, and though in ill-health at the time, he made the acquaintance of most of the eminent medical men in Edinburgh, London and Paris; he also made many observations in respect to the institutions pertaining to Medicine located in these cities. Immediately after his return from Europe, in May, 1855, he came to California, and located in San Francisco. His purpose in coming here, was two-fold, first, the improvement of his health, which had been shattered by a too uninterrupted application to business, and, second, to find an ampler field for the exercise of his surgical talent, and besides, an ulterior object was, that, at no remote day, California would have, as one of her wants, the establishment of a medical school on the shores of the Pacific. . . .

Soon after coming to this coast, he was attacked with an obscure nervous affection, which manifested itself by an attack of left hemiplegic facial paralysis, and wandering neuralgic pains in the extremities, with indigestion.

There can be no doubt that facial palsy accompanied by recurrent neurologic and digestive symptoms would be a significant handicap to a young physician newly arrived in the maelstrom that was San Francisco in 1855. Political corruption and crime in the streets were rampant. There was a surplus of physicians, and an additional doctor was looked upon by those already present as an unwelcome intruder. This would be especially true in the case of a newcomer with the aggressiveness and pretensions of Elias Cooper. He indicates from time to time during the following years that he is unwell, but provides insufficient detail to allow us to hazard a diagnosis. Although we lack specifics, we should keep in mind when considering his behavior and achievements during his residence in San Francisco that he was burdened throughout by a serious and progressive chronic illness.[65]
