This autobiography relates Rush's experiences in college and medical school; his meetings with notable doctors; his life in Scotland, England, and France; his medical views; the military and politics during the Revolutionary War; and brief sketches of personalities of that period.

Personal and professional correspondence of the chemist Robert Hare, including drafts of letters to editors of journals on such varied topics as fish guano, slaughterhouses, paper money, and the meaning of the term "Yankee annexations." The collection originally contained over 300 scrolls, since disbound, which contained drafts of letters, essays, and lectures, composed by Hare on ordinary sheets of paper, then pasted end to end, and rolled up. The essay and lecture topics include: chemistry, storms, slavery, currency, fire-fighting, capital punishment, railroads, the Smithsonian Institution, Michael Faraday, religion and Spiritualism, riots in Philadelphia, epidemics, underwater blasting, and Ralph W. Emerson; there is some verse. The collection also contains an account book of Hare and his wife, 1806-1829 (180 pp.; B/H22#3); a volume by Hare on Cyclones (tornadoes), n.d. (ca. 60 pp.; B/H22#4); and Samuel Powel, Jr.'s "Short notes on a course of antiquities at Rome... under M. Byre Antiquarian," 1764. (60 pp.).

Simon Flexner, born in 1863, one of the nation's leading experts in pathology and bacteriology, was most renowned for his research on cerebrospinal meningitis, polio and infantile paralysis. Arguably though, Flexner's stewardship of the Rockefeller Institute was his greatest contribution to medical and scientific research. His rise in the medical community began in the late nineteenth century in Louisville, Kentucky, where despite not having completed even the seventh grade, Flexner taught himself basic bacteriology by conducting experiments at home using a microscope borrowed from the pharmacy where he served as an apprentice. Granted a medical degree from the University of Louisville School of Medicine in 1889, he went on to a pathology fellowship at the newly opened John Hopkins School of Medicine. Within two short years of leaving Louisville, Flexner received an assistant of pathology appointment at Johns Hopkins. It was a quick ascent and the beginning of a long and brilliant career that included a prestigious appointment at the University of Pennsylvania and then a directorship at the new Rockefeller Institute where he realized his lifelong dream of creating a dynamic and productive research laboratory. The Rockefeller Institute became instantly famous worldwide as the preeminent research facility for virology and under Flexner's direction produced invaluable contributions in pathology, bacteriology, and immunology. This collection does not reflect the early phases of Flexner's career at Johns Hopkins but does document an early interest in meningitis and other infectious diseases with science-related correspondence, laboratory notebooks, and administrative correspondence with the New York City and State Departments of Health. There is abundant material on Flexner's directorship of the Rockefeller Institute for Medical Research, including Flexner's search for staff, an involved process which is detailed in correspondence with the scientists, many of whom became quite famous. Also included is material relating to the other institutions and Rockefeller philanthropies with which Flexner was involved. (Among the most significant correspondence, however, may be that which documents the support of the General Education Board and the Rockefeller Foundation in the development and subsequent reorganization of medical schools following brother Abraham Flexner's scathing report on medical education in the United States and Canada). This collection would be of great interest to anyone interested in the history of bacteriology, histology, and immunology or the general history of modern medicine and philanthropy.
