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.
