Kurt Lewin
Kurt Zadek Lewin (September 9, 1890 – February 12, 1947) was a German-American psychologist, known as one of the modern pioneers of social, organizational, and applied psychology in the United States. Kurt Lewin, exiled from the land of his birth, made a new life for himself. In this new life, Lewin 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 (/ləˈviːn/ lə-VEEN) is often recognized as the "founder of social psychology" and was one of the first to study group dynamics and organizational development.
