U.S. sociologist.
Riesman taught at the universities of Buffalo and Chicago before returning to Harvard, his alma mater, to teach (195880). He studied primarily the social character of the urban middle class and is noted for The Lonely Crowd (1950), the title of which became a catchphrase for the alienation of the individual in modern urban society.
