LEWIS, Dio, physician, born in Auburn, New York, 3 March, 1823; died in Yonkers, New York, 21 May, 1886. He studied at the Harvard medical school, and, adopting homoeopathy, practised it for several years in Buffalo, New York, where he also edited and published a medical magazine in which he deprecated the use of drugs and advocated physical exercise as a part of public education. From 1852 till 1863 he was engaged in lecturing on hygiene and physiology, and at the latter date he settled in Boston and founded the Boston normal physical training school, at which, in seven years, five hundred pupils were graduated. His influence had much to do with the establishment of the present system of physical culture in most of the institutions of learning in the United States. In 1864 he established in Lexington, Massachusetts, a school for young women which was based on hygienic principles, but in September, 1868, the buildings were burned, and the next year the school was given up. He then resumed lecturing, principally on hygiene and temperance, and originated the women's temperance crusade in Ohio. He edited "Today," "Dio Lewis's Monthly," "Dio Lewis Nuggets," and the "Dio Lewis Treasury," the latter being put to press immediately before his death. He published. besides numerous pamphlets and papers in magazines, "New Gymnastics" (Boston, 1862); "Weak Lungs, and how to make them Strong" (1863); "Talks about People's Stomachs" (1870); "Our Girls" (New York, 1871); "Chats with Young Women" (1871); "Chastity" (1872); "Gypsies" (1881); and "In a Nutshell" (1883).
