Henry S. Tanner

Henry S. Tanner was an American physician noted for a highly publicized prolonged fasting demonstration in the late 19th century that sparked debate across medical, scientific, journalistic, and religious communities. His career intersected with institutions, publications, and public figures in Philadelphia, New York, and international scientific circles, provoking responses from physicians, newspapers, reformers, and skeptics. Tanner’s life and claims engaged topics connected to medical education, public health debates, temperance movements, and popular science discourse.

Early life and education

Tanner was born in Philadelphia and pursued medical training consistent with mid-19th century practices that connected institutions such as the University of Pennsylvania, the College of Physicians of Philadelphia, and hospitals like Pennsylvania Hospital. His formative period overlapped with figures and institutions including Benjamin Rush, Jefferson Medical College, University of Pennsylvania School of Medicine, Philadelphia Academy of Natural Sciences, and contemporaneous movements associated with Andrew Jackson-era public life. Early influences included medical reform debates that involved actors such as Samuel Hahnemann in alternative medicine circles, and the rise of professional organizations like the American Medical Association and the American Public Health Association.

Medical career and practice

During his practice Tanner engaged with a medical community interacting with hospitals, clinics, and academic journals such as the New England Journal of Medicine, the British Medical Journal, and the Lancet. Tanner’s work and public profile brought him into contact—directly or indirectly—with prominent medical figures and institutions including William Osler, Harvey Cushing, John Shaw Billings, Thomas Addis Emmet, and the era’s leading hospitals like Bellevue Hospital and Massachusetts General Hospital. Debates about fasting and nutrition in which Tanner participated involved associations and publications such as the American Medical Association, the Royal Society of Medicine, the Royal Society, and periodicals including the New York Times, the Chicago Tribune, and Scientific American. His clinical opinions were discussed alongside public health topics handled by municipal bodies such as the New York City Department of Health and state-level entities like the Pennsylvania Department of Health.

Breatharian fasting demonstration and public reaction

Tanner became widely known after announcing and conducting a prolonged fast in New York City that prompted coverage from major newspapers, medical journals, and the public. The demonstration elicited commentary from editors and writers at the New York Daily Tribune, the New York Herald, the New York Sun, and the Harper's Weekly, and was critiqued in scientific forums such as the Royal Society of London, the American Philosophical Society, and meetings of the New York Academy of Medicine. Responses ranged from skeptical analyses by physicians affiliated with Columbia University, Cornell University, and Johns Hopkins University to interest from social reformers linked to the Temperance Movement, the Vegetarian Society, and advocates associated with the Seventh-day Adventist Church and other religious communities. Public figures including journalists, temperance advocates, and scientists referenced Tanner in discussions that included comparisons to fasting practices reported for figures such as Mahatma Gandhi, ascetic practices noted in accounts of Saint Francis of Assisi, and investigations reminiscent of earlier naturalist examinations by travelers affiliated with the Royal Geographical Society and explorers like David Livingstone. International reactions involved commentary in journals connected to the Société de Biologie and the Institut Pasteur milieu, while skeptics invoked methods discussed in magicians’ circles such as those surrounding Harry Houdini and exposés in Puck (magazine) and other satirical outlets.

Later years and legacy

In later life Tanner remained a figure cited in histories of nutrition, dietetics, and popular medicine. His case was referenced in academic treatments spanning disciplines and institutions including the Johns Hopkins Bloomberg School of Public Health, the Harvard T.H. Chan School of Public Health, and the archives of the Wellcome Trust. Writers on the history of medical charlatanism and scientific skepticism compared Tanner to figures discussed in works about Franz Mesmer, Phineas Parkhurst Quimby, and critics like Thomas Wakley of the Lancet. Tanner’s demonstration influenced discussions in later 20th-century movements addressing fasting and alternative health, intersecting with authors and organizations such as Herbert Shelton, the Health and Temperance Movement, the American Dietetic Association, and commentators in Time (magazine) and The Atlantic. His legacy appears in museum collections, historical monographs, and university special collections alongside materials related to the development of modern clinical trials at institutions like the Clinical Center (NIH).

Personal life and beliefs

Tanner’s personal convictions about fasting, diet, and health were situated amid contemporaneous cultural networks that included temperance advocates, vegetarian circles, and religious reformers. His views were discussed in pamphlets and periodicals distributed by publishers and societies such as the Vegetarian Society (United Kingdom), the American Vegetarian Society, and reform-oriented presses tied to figures like Horace Greeley and William Lloyd Garrison. Correspondence and commentary about his life connected with clerical figures and reformers from offices in cities like Philadelphia, New York City, and Boston, and with contemporaries in scientific and medical societies, including the American Philosophical Society and the New York Academy of Sciences. Tanner died in 1919, and his papers and press coverage remain a subject of interest for historians working in archives at institutions such as the Library of Congress, the New-York Historical Society, and university special collections.
