Lewis, Oscar, 1914–70, American anthropologist, b. New York City, grad. City College of New York (B.S.S., 1936) and Columbia (Ph.D., 1940). He was a professor of anthropology at Washington Univ. (St. Louis) from 1946 to 1948 and after that at the Univ. of Illinois. His theory of the culture of poverty holds that the poor in modern capitalist societies represent an identifiable culture that transcends national differences, and that the social and psychological consequences of poverty are severe and difficult to overcome. Much of his work describes the lives of poor Hispanics in the United States and Latin America. Among his works are Five Families (1959), The Children of Sánchez (1961), La Vida (1966), and Anthropological Essays (1970).
