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.

Lewin (pronounced /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.Lewin's equation

The Lewin's Equation, B=ƒ(P,E), is a psychological equation of behavior developed by Kurt Lewin. It states that behavior is a function of the person and their environment [10].

The equation is the psychologist's most well known formula in social psychology, of which Lewin was a modern pioneer. When first presented in Lewin's book Principles of Topological Psychology, published in 1936, it contradicted most popular theories in that it gave importance to a person's momentary situation in understanding his or her behavior, rather than relying entirely on the past.
