Frederic Milton Thrasher (1892 - March 24, 1962) was an American sociologist. Birb ub Shelbyville, Indiana, he graduated with a bachelor's degree in social psychology from DePauw University in 1916. He then completed a M.A. and a Ph.D. at the University of Chicago, completing the latter in 1926. Thrasher's magnum opus The Gang: A Study of 1,313 Gangs in Chicago, which was based on his doctoral dissertation, was published in 1927. Robert E. Park served as his advisor while Thrasher studied at the University of Chicago, and the success of The Gang made him one of the most prominent members of the Chicago School of Sociology in the 1920s. In 1927, Thrasher accepted a teaching position at the Steinhardt School of Education at New York University in New York City. While at NYU, Thrasher began a media studies program and focused his research on the effects of motion pictures on children. Thrasher held the position of Professor of Educational Sociology at NYU until he retired in 1959.
