Benjamin Rush

Benjamin Rush (1746—1813) was the most influential American physician of the early republic, a signer of the Declaration of Independence, and the figure whose therapeutic convictions shaped regular medical practice in the United States for more than a generation. He reduced disease to a single cause — hyperexcitation of the arterial system — and prescribed accordingly: massive bloodletting and mercury purges. His political stature and rhetorical force gave these practices an authority they would not otherwise have achieved. He was also a reformer of asylums, an early advocate for viewing alcoholism as a disease, and a tireless promoter of American botanical medicine. Historians give him credit for enormous energy and genuine concern for the sick, while acknowledging that his therapeutics were, in Ackerknecht’s phrase, “no less murderous for being honest.”

Life and Formation

Rush studied at the College of Philadelphia before travelling to Edinburgh, where he trained under William Cullen (Haller, 1981). Edinburgh was then the leading center of medical instruction in the English-speaking world, attracting 17,000 students in its first century and offering practical training in English without religious restrictions (Porter, 1997). The Edinburgh school’s emphasis on first principles rather than empirical observation became the intellectual foundation for Rush’s later system-building (Haller, 1981). Haller in American Medicine in Transition identifies Cullen’s influence directly: the speculative pathology behind America’s rationalist use of calomel derived from the Edinburgh School, which taught that first principles — not observation of the processes of life — were the foundation of successful therapeutics (Haller, 1981).

Rush returned to Philadelphia and joined the faculty of the Medical Department of the College of Philadelphia, the first medical school in North America, which offered a two-year graded curriculum including clinical lectures (Haller, 1994). He signed the Declaration of Independence and remained a public figure throughout his life. From 1769 to 1822, every major English-language publication on medical ethics was authored by physicians trained at Edinburgh, and Rush’s lectures on medical duties were part of this tradition (Baker, 2013).

Medical System

Rush’s pathology was radically monistic (Ackerknecht, 1955). Ackerknecht describes him as producing “a variation of John Brown’s system, in which, as a consistent monotheist, he reduced the number of diseases from two to one” (Ackerknecht, 1955). Rush concluded that a hyperactive state of the arteries, which he called “hypertension,” was the key to disease (Porter, 1997). This dictated an aggressively depletive therapeutics consisting of copious bloodletting (Porter, 1997).

Warner, in The Therapeutic Perspective, captures the stance precisely: Rush epitomized the aggressive interventionist position in early-nineteenth-century American medicine, believing physicians should actively cut short disease with bloodletting and large doses of drugs (Warner, 1986). Nature, in Rush’s view, was not a healer but a menace. He told his students that in violent diseases, nature was like “a drunken man reeling to & fro &. occasionally stumbl[ing] against a door with so much violence as to break it through” (Warner, 1986). Haller’s description is blunter: Rush “had no confidence in Mother Nature, and insisted that she be driven from the sick room as one would a stray dog or cat” (Haller, 1981). Whorton’s primary-source account confirms the image precisely: students at the University of Pennsylvania recorded Rush advising them to “always treat nature in a sick room as you would a noisy dog or cat — drive her out at the door and lock it upon her.”(Whorton, 2002) The phrase belongs to the students’ notebooks, not to any published text, which is why the quote appears in paraphrase across secondary sources but rarely in Rush’s own words.

Whorton notes that calomel was a frequently prescribed purgative in early nineteenth-century American medicine, but its toxicity caused severe oral damage (Whorton, 2002). Rush argued that European bleeding practices were inadequate for American diseases and ordered “ten and ten” of calomel and jalap along with repeated bleedings (Haller, 1981).

The 1793 Yellow Fever Epidemic

The Philadelphia yellow fever epidemic of 1793 killed nearly 5,000 residents and drove over 17,000 to flee the city.(Powell, 1949) Rush treated as many as 120 patients a day while his wife and children remained safely in New Jersey, becoming a popular hero for his dedication.(Powell, 1949) He believed passionately in his cure of radical bloodletting and mercury purging even as his own sister and three of his apprentices died of the disease under his roof.(Powell, 1949)

During the epidemic, Rush and his colleague Phillip Physick practiced extreme bloodletting, making single bleedings of one hundred ounces and more (Haller, 1981). In his “Defense of Bloodletting,” Rush insisted that four-fifths of a patient’s blood could be abstracted without causing harm (Haller, 1981). He argued that standard European bleeding practices were woefully inadequate for the particular harshness of American diseases, justifying uniquely heroic American therapeutics (Haller, 1981).

After the epidemic, Rush became the leader of American anticontagionists, maintaining that yellow fever arose from local environmental causes rather than imported contagion (Ackerknecht, 1955). This position had practical consequences: anticontagionism favored sanitary reform over quarantine, aligning with the commercial interests of Philadelphia’s merchants who opposed trade restrictions.

Powell’s social history of the epidemic reconstructs Rush’s role in detail, and the account complicates the heroic portrait Rush later promoted.

Rush had not begun with the Ten-and-Ten. In the epidemic’s first weeks he tried gentle purges and mild bleedings, cool air, and cold baths — none of which produced results (Powell, 1949). His therapeutic pivot came from an old manuscript that Benjamin Franklin had given him years earlier: John Mitchell’s 1741 account of yellow fever in Virginia, which argued that physicians must “domineer over” rather than assist nature, and that abdominal viscera choked with blood must be evacuated immediately (Powell, 1949). Mitchell’s text broke Rush’s thinking open. He described the moment in terms that reveal how much his medical convictions rested on prior philosophical commitments: “Never before did I experience such sublime joy as I now felt in contemplating the success of my remedies. It repaid me for all the toils and studies of my life… it was the triumph of a principle in medicine” (Powell, 1949). The principle — physician dominance over passive nature — already had a home in Rush’s system. Mitchell gave him a rationale and a drug.

The drug was Thomas Young’s wartime formula: ten grains of calomel and ten of jalap, administered together (Powell, 1949). Rush first tried it secretly on August 29 on a man alone in a shuttered house, apparently dying and abandoned by his family. The man improved (Powell, 1949). By September 3 Rush was informing the Fellows of the College of his cure; he claimed to have recovered eight of twelve patients on the first day of treatment, then nine of ten, then twenty-nine of thirty (Powell, 1949). These escalating claims struck contemporaries as improbably optimistic (Powell, 1949).

Dr. Adam Kuhn held that yellow fever was a putrid rather than inflammatory disease (Powell, 1949) and prescribed a cure involving no purge except for costiveness, camomile tea, and cool water baths twice daily (Powell, 1949). Dr. Edward Stevens arrived from St. Croix with the same tonic-not-depletive philosophy, advocating cordial tonic remedies and cool baths while opposing bleeding and purging (Powell, 1949). William Currie published the first systematic account of the epidemic, stating infection was caused by bodily contagion and rejecting bleeding (Powell, 1949).

Dr. Philip Physick contracted yellow fever during the epidemic and was treated by William Potts Dewees following Rush’s regimen: twenty-two bleedings totaling 176 ounces of blood, a quantity both men believed responsible for his recovery (Powell, 1949). Dr. James Hutchinson, the Port Physician, died on September 6 after declining Rush’s mercury purge; Rush attributed the death to this refusal and to the mild Cullenian treatment his attending physicians had substituted (Powell, 1949).

The epidemic exposed and widened existing fault lines in Philadelphia’s medical profession. Rush accused his colleagues who used bark and wine of murder (Powell, 1949). By October the conflict had become bitter enough that Rush sent a formal letter to Dr. Hodge declaring that the difference in their therapeutic principles made future consultation “impossible… with Safety to a patient,” and comparing the prospect of their consulting together to “a Jew and a Christian attempting to worship in the same temple” (Powell, 1949). The specific medical harms of mercury were contested in real time: Dr. Duffield accused Rush’s powders of having “ruined” a sixteen-year-old girl patient, but Rush dismissed this as malice from a follower of Kuhn, acknowledging mercury’s unpleasant effects — it dried the mouth and stained the teeth — while denying it could accomplish serious harm.(Powell, 1949) Rush declared that future consultation with his opponents was impossible: “After what has passed between me and the rest of them, we can never consult, or even associate together.”(Powell, 1949) He severed relations with Kuhn, Currie, and eventually his own loyal colleague Caspar Wistar, who published a recovery account that credited multiple physicians and admitted he had taken only half Rush’s prescribed doses — a moderate report Rush received as betrayal (Powell, 1949).

Rush’s public standing also shifted over the epidemic’s course. Merchant John Welsh reported that Rush’s calomel regimen initially attracted wide popular attention but that as cases failed to improve, the “great talk about it” died away; by the epidemic’s end the mercurial purge was “held in the lowest esteem, particularly as it destroyed the coat of the stomach and bowels” (Powell, 1949). Rush insisted he was being publicly accused of murder at every corner (Powell, 1949) and invoked popular democracy to override professional dissent: “the people rule here in medicine as well as government” (Powell, 1949). Powell’s own review of Andrew Brown’s Federal Gazette, however, found far more favorable notices of mercury and bleeding than critical ones — suggesting, as Powell puts it, that Rush “magnified doubts into enmity” (Powell, 1949).

By late October a practical compromise had emerged without Rush’s endorsement: most physicians were bleeding and purging at the onset of fever, then switching to bark, wine, and nourishing food once the acute phase broke (Powell, 1949). Rush would not accept half-measures (Powell, 1949).

The epidemic also forced a reckoning with class and race in Philadelphia. Powell, drawing on Mathew Carey’s contemporary account, noted that seven of eight who died were poor, and that at least a third of those deaths followed from lack of access to treatment of any kind (Powell, 1949). Rush recruited the Free African Society — founded in 1787 by Absalom Jones and Richard Allen as a mutual aid organization — by arguing that Black Philadelphians had been granted special immunity from the disease and therefore had a particular obligation to assist (Powell, 1949). Jones, Allen, and William Gray trained under Rush’s direction; they ultimately bled over eight hundred patients following his prescriptions (Powell, 1949). By mid-September, however, Black Philadelphians were contracting the fever in large numbers, disproving the immunity Rush had claimed and that had grounded his recruitment appeal (Powell, 1949). Carey’s subsequent pamphlet accused Black nurses of profiteering and plunder; Jones and Allen responded with their own narrative documenting white misconduct and recording that the Society ended the epidemic with a deficit of £177/9/8 — evidence that they had frequently buried the poor without charge (Powell, 1949) (Powell, 1949).

Clinical Practice

Rush’s application of his mechanical and depletive principles extended to the treatment of the insane. For patients at the Pennsylvania Hospital, he devised a chair he called “The Tranquillizer” — a device that “binds and confines every part of the body.” Rush described its rationale in terms wholly consistent with his general pathology: “By keeping the trunk erect, it lessens the impulse of blood toward the brain. By preventing the muscles from acting, it reduces the force and frequency of the pulse.” He was pleased with the results: “Its effects have been truly delightful to me. It acts as a sedative to the tongue and temper as well as to the blood vessels.” (Andrew Scull, 2015) As Scull notes in Madness in Civilization, the Tranquillizer exemplifies the era’s mechanical therapeutic imagination applied to madness — its inventor saw restraint not as punishment but as a somatic intervention continuous with bleeding and purging.

Griggs provides a concrete case from the diary of Elizabeth Drinker, whose husband Henry — a Philadelphia Quaker — was treated by Rush for dysentery in 1807. Over five weeks Rush ordered repeated bleedings totaling over twenty-two ounces, blisters on both wrists, multiple enemas, and opium injections (Griggs, 1981). Elizabeth recorded this as perfectly ordinary care, suggesting how thoroughly Rush’s methods had become normalized in genteel Philadelphia.

A Boston physician of the mid-eighteenth century described local medical practice in terms: “bleeding, vomiting, blistering, purging, anodyne, etc. if the illness continued there was repetendi, and finally murderandi” (Griggs, 1981). A French tourist in 1788 confirmed that American practice was “the English practice, that is, they are much in the use of violent remedies” (Griggs, 1981). Porter observes that the therapeutic nihilism of Paris medicine was “hopeless for a nation of intrepid pioneers” and that, following Rush’s lead, regulars went to the opposite extreme, making heroic therapeutics their trademark (Porter, 1997).

Reformer and Moralist

Rush’s influence extended beyond therapeutics. He urged the study of America’s indigenous plants, arguing that American flora might furnish the world with cures that eluded European medicine (Haller, 1994). He told students to cultivate indigenous medicines and “endeavor to enlarge the materia medica, by exploring the untrodden fields and forests of the United States” (Haller, 1994).

Temkin, in The Double Face of Janus, traces Rush’s classification of alcoholism as a disease (Temkin, 1977). Rush combined moral and physical treatment, blurring the boundary between disease and vice as Enlightenment physicians entered middle-class civic life (Temkin, 1977). Rush felt the necessity to justify treating a disease induced by an act of vice, and his apology echoed Sydenham’s a century earlier (Temkin, 1977).

Rush’s lectures on the duties of physicians were part of a broader Edinburgh-derived tradition of medical ethics. Baker identifies the period from 1769 to 1822 as one in which every major English-language publication on medical ethics was authored by Edinburgh-trained physicians (Baker, 2013). Samuel Bard, another Edinburgh graduate, brought the practice of lecturing on medical ethics back to colonial New York; his “Discourse on the Duties of a Physician,” delivered at the first medical commencement at King’s College in 1769, was the first American publication on medical ethics (Baker, 2013). Rush’s own ethical writings contributed to the tradition that would culminate in the AMA’s 1847 Code of Medical Ethics, drafted by a committee that drew on Rush’s lectures, Percival’s code, and Gregory’s writings (Haller, 1981).

Rush’s Medical Inquiries and Observations upon the Diseases of the Mind (1812) was the first American textbook of psychiatry and the culmination of his asylum work at the Pennsylvania Hospital. It systematized the same monistic pathology that governed his general medicine: mental disturbance arose from the same hyperexcitation of the vascular system that caused other diseases, and required the same depletive remedies — bloodletting, purging, the Tranquillizer. The book’s influence on American asylum medicine was substantial, though its specific doctrines were largely abandoned by the 1830s as Paris-trained physicians began insisting on observation over system.

Political Order and Health

Rosen’s essay on Jeffersonian thought in From Medical Police to Social Medicine (1974) positions Rush as the American Enlightenment’s most forceful theorist of the relationship between political institutions and health. Rush argued in 1774 that disease, political institutions, and economic organization were so interrelated that any general social change produced accompanying changes in health.(Rosen, George, 1974) He claimed an “indissoluble union between moral, political and physical happiness,” arguing that “elective and representative governments are most favourable to individual as well as national prosperity” and therefore most favorable to animal life.(Rosen, George, 1974) The Jeffersonian premise from which both Rush and Jefferson worked held that the Creator had designed the human body to flourish in harmony with its political and social environment, and had framed the political order to promote human health.(Rosen, George, 1974)

Rush offered historical evidence for the thesis. The abolition of feudalism, he argued, by introducing freedom and consequently agriculture, had eliminated leprosy, elephantiasis, and other disorders that afflicted servile populations — making political slavery literally pathogenic, deforming and debasing the human body.(Rosen, George, 1974) This was not merely rhetorical: it was a theory of how political structure shaped the material conditions of life, and thus health. Rush extended the argument across his career, connecting American republican institutions to healthier bodies in ways that reinforced his insistence on an active medicine capable of assisting the body’s inherently Republican capacities.

Jefferson viewed the yellow fever epidemics that struck American cities in the 1790s as providential warnings against urbanization.(Rosen, George, 1974) He wrote that “the yellow fever will discourage the growth of great cities in our nation, and I view great cities as pestilential to the morals, the health and the liberties of man.”(Rosen, George, 1974)

In letters to his wife Julia during the epidemic, Rush confessed that he had sometimes found himself willing to die if his death would advance the “great objects” to which he had directed himself, finding consolation in her prudence and faith that she could properly raise their children without him.(Powell, 1949) The remark captures the self-sacrificial element in Rush’s professional identity — his medical commitments were inseparable from a religious and civic mission.

The argument’s practical implication was that reform of political institutions was a legitimate public health measure — an idea that connects Rush to the Virchow tradition in German social medicine, though arrived at through different intellectual routes.

Legacy and Historiographic Assessment

Henry Ingersoll Bowditch, reviewing the first century of American medicine in 1876, placed Rush squarely in the “epoch of systems” — the era from 1776 to 1832 dominated by confidence in art and distrust of nature, typified by the systems of Cullen, Brown, Rush, and Broussais (Warner, 1986). The second epoch, that of observation inaugurated by the Paris clinical school, was in Bowditch’s account “chiefly destructive” — it demolished the speculative systems but contributed little positive to therapeutics (Warner, 1986).

Rush was bestowed the title “American Sydenham” by devoted friends, though Ackerknecht notes this designation “is somewhat exaggerated” (Ackerknecht, 1955). He reduced John Brown’s two disease categories to one and recommended heroic bloodletting and purging, which the author described as “no less murderous for being honest” (Ackerknecht, 1955). After Brown’s death, the system’s simplification of diagnosis and therapeutics brought it many adherents and made it an important component of early nineteenth-century medical practice (Coulter, 1975). Louis’s numerical method dismantled rationalistic beliefs embedded in the practice of bleeding and the heroic uses of calomel and tartar emetic, ushering in an expectant regimen of healing (Haller, 2014). William Cullen at Edinburgh introduced clinical lectures into medical instruction and became one of the foremost British clinicians, developing a nosology of fevers (Haller, 1994).
