John (Collins) Warren

Surgeon, born in Boston, Massachusetts, USA. The son and nephew of famous Boston doctors, he studied surgery with his father John Warren (1753–1815) and then completed his studies in Europe. He set up a practice in Boston (1802) and was on the faculty of the Harvard Medical School for most of his career (1809–47). Active in reforming medical education and practice in America, he was one of the founders of Massachusetts General Hospital, where (16 Oct 1846), he performed the first operation using ether as an anesthesia (with William Morton administering it). The first American to operate on a strangulated hernia, he wrote an important book on his speciality, Surgical Observations on Tumours (1837).
