Karl Duncker

Karl Duncker was a German Gestalt psychologist. He attended Friedrich-Wilhelms-University from 1923 to 1923, and spent 1925–1926 at Clark University in Worcester, MA as a visiting professor, where, in 1926, he received a master in arts degree. Until 1935 he was a student and assistant of the founders of Gestalt psychology in Berlin: Max Wertheimer, Wolfgang Köhler and Kurt Koffka. In 1935, exiled by the Nazis, he got an assistantship in Cambridge with Frederic Charles Bartlett and later emigrated to the US, where he was again an assistant of Wolfgang Köhler's at Swarthmore College. Duncker committed suicide in 1940 at 37 years of age having suffered from professionally treated depression for some time.
