Richard Louis Dugdale

From Wikipedia, the free encyclopedia

Richard Louis Dugdale (1841-1883) was an American sociologist.

He was born in Paris to English parents, and moved with them to New York in 1851. He is most noted for his work The Jukes: A Study in Crime, Pauperism, Disease and Heredity (see Jukes and Kallikaks) in which he supposedly found that criminality was heritable (see eugenics). This view is no longer supported today.
