Kurt Lewin

Kurt Lewin ( lə-VEEN; 9 September 1890 – 12 February 1947) was a German-American psychologist, known as one of the modern pioneers of social, organizational, and applied psychology in the United States. Exiled from the land of his birth, Lewin made a new life for himself, in which he defined himself and his contributions within three lenses of analysis: applied research, action research, and group communication were his major offerings to the field of communication. Lewin is often recognized as the "founder of social psychology" and was one of the first to study group dynamics and organizational development. A Review of General Psychology survey, published in 2002, ranked Lewin as the 18th-most cited psychologist of the 20th century.
