Kurt Lewin was born in 1890 an area of Prussia that is now part of Poland. He earned his doctorate under Carl Stumpf at the University of Berlin in 1916. After serving in the German Army during World War I, Lewin returned to the academic world. An appointment to the Psychological Institute in 1921 brought him into close association with the Gestalt psychologists Koehler and Wertheimer. He was particularly associated with Koehler, who had succeeded Stumpf as director of the Institute. Lewin’s position was that of untenured faculty member at the Institute.
