Herbert J. Gans (born May 7, 1927) is a German-born American sociologist who taught at Columbia University from 1971 to 2007. One of the most prolific and influential sociologists of his generation, Gans came to America in 1940 as a refugee from Nazi Germany and has sometimes described his scholarly work as an immigrant's attempt to understand America. He trained in sociology at the University of Chicago, where he studied with David Riesman and Everett Hughes, among others, and in social planning at the University of Pennsylvania, where his dissertation was supervised by Martin Meyerson. Herbert J. Gans served as the 79th President of the American Sociological Association. Source: Wikipedia (en)
