ELLIOTSON, JOHN (1791-1868), English physician, was born at Southwark, London, on Oct. 29, 1791. He studied medi cine at Edinburgh, Cambridge, and subsequently in London at St. Thomas's and Guy's hospitals. In 1831 he was elected pro fessor of the principles and practice of physic in London uni versity, and in 1834 he became physician to University college hospital. His interest in mesmerism eventually brought him into collision with the medical committee of the hospital, and he re signed his offices in 1838. In 1849 he founded a mesmeric hos pital. He died in London on July 29, 1868. Elliotson was one of the first teachers in London to appreciate the value of clinical lecturing, and one of the earliest among British physicians to advocate the employment of the stethoscope. He contributed numerous papers to the Transactions of the Medico-Chirurgical Society, of which he was at one time president ; he was founder and president of the Phrenological Society. W. M. Thackeray's Pendennis was dedicated to him.
