Born 13 Oct 1867; died 16 Aug 1941 at age 73.
William Zebina Ripley was an American economist and anthropologist whose early book The Races of Europe: A Sociological Study (1899) directed the attention of American social scientists to the existence of subdivisions of geographic races. He gave broad classifications of the European Caucasians into three local races: the northern (Teutonic) and southern (Mediterranean) populations are probably of extremely ancient origin, but the central (Alpine) group has descended from more recent migrants from Asia. Ripley was trained in civil engineering, though he spent most of his career as professor of political economy. In 1920-23 he drew up for the Interstate Commerce Commission the Ripley Plan for the regional consolidation of U.S. railways.
