RANDOLPH, Jacob, physician, born in Philadelphia, 25 November, 1796; died there, 12 April, 1836. His ancestor, Edward Fitz-Randolph, emigrated to this country from England in 1630. His father was an officer in the 4th Pennsylvania regiment during the Revolution, but subsequently became a member of the Society of Friends, and dropped the prefix from his fan lily name. Jacob studied at the Friends' school, was graduated at the University of Pennsylvania in 1817, and became surgeon on an American ship that was bound for Canton, China. Afterward he returned to Philadelphia and settled in the practice of his profession in that city in 1822, in which year he married the daughter of Dr. Philip Syng Physick. He was appointed surgeon to the Almshouse infirmary and lecturer on surgery in the Philadelphia school of medicine in 1830. From 1835 until his death he was a surgeon to the Pennsylvania hospital. He was in Europe in 1840-'42, spending most of his time in the surgical departments of the Paris hospitals. During his absence he declined the chair of surgery in Jefferson medical college. Dr. Randolph became lecturer on clinical surgery in the University of Pennsylvania in 1843, and professor of that branch in 1847. Meanwhile he had acquired a wide reputation as a surgeon, and in 1831 introduced in the United States the operation of lithotripsy. He was a member of the American philosophical society, of the Philadelphia college of physicians, and of the Philadelphia medical society, and was consulting surgeon to the Philadelphia dispensary. He published several reports of successful operations for stone in the bladder by lithotripsy, "History of a Case of Femoral Aneurism in which the Femoral Artery was tied for the Second Time in the Medical History of Philadelphia," in the "North American Medical and Surgical Journal "(1829), and a "Memoir of Philip Syng Physick" (Philadelphia, 1839). See a memoir of him by George W. Norris (1848).--His great-nephew, Nathaniel Archer, physician, born in Chadd's Ford, Pennsylvania, 7 November, 1858; died in Longport, New Jersey, 22 August, 1887, was educated at Swathmore college, Pennsylvania, and at Cornell, and was graduated at the medical department of the University of Pennsylvania in 1882. The same year he was appointed assistant demonstrator and lecturer on anatomy there, becoming professor of hygiene in 1886. Dr. Randolph's early death by drowning cut short a brilliant career. He was a member of many scientific societies, a contributor to scientific periodicals, and, with Samuel G. Dixon, published "Notes from the Physiological Laboratory of the University of Pennsylvania" (Philadelphia, 1885).
