Edwin Hardin Sutherland (August 13, 1883 – October 11, 1950) was an American sociologist. He is considered one of the most influential criminologists of the 20th century. He was a sociologist of the symbolic interactionist school of thought and is best known for defining white-collar crime and differential association, a general theory of crime and delinquency. Sutherland earned his Ph.D. in sociology from the University of Chicago in 1913. In 1939 Edwin was the first who introduced White Collar Crime. Career Sutherland's historical importance rests upon his having introduced (in a 27 December 1939 speech to the American Sociological Association, titled The White Collar Criminal) the concept of white-collar crime, a concept which violated existing prejudices that aristocrats can do no wrong (which was famously expressed in the ancient legal view that a king could do no wrong). After receiving his PhD from the University of Chicago, Sutherland was at William Jewell College, Missouri (1913–1919), the University of Kansas (the summer of 1918), University of Illinois (1919–1925), Sutherland spent a summer at Northwestern (June–August 1922) prior to arriving at the University of Minnesota in 1925. Sutherland solidified his reputation as one of the country's leading criminologists at the University of Minnesota, where he worked from 1926 to 1929. During this period, he concentrated in sociology as a scientific enterprise whose goal was to understand and control social problems. For several months in 1929 Sutherland studied the British penal system while in England. Also, during 1929–1930 Sutherland worked as a researcher with the Bureau of Social Hygiene in New York City. In 1930, Sutherland accepted a position as a research professor at the University of Chicago. In 1935 he took a position at Indiana University, where he remained till his untimely death on October 11, 1950. He founded the Bloomington School of Criminology at Indiana University. During his time at Indiana, he published four books, including Twenty Thousand Homeless Men (1936), The Professional Thief (1937), the third edition of Principles of Criminology (1939), and the censored first edition of White Collar Crime (1949), his masterpiece. It remained censored until the original text was published in 1983 by Yale University Press. Sutherland was elected president of the American Sociological Society in 1939, and president of the Sociological Research Association in 1940.
