Kurt Lewin

Kurt Lewin was a prominent psychologist known for his contributions to social psychology and organizational development. He introduced the concept of "group dynamics," which examines how people behave in groups. Lewin is famous for his "change model," consisting of three stages: unfreezing, changing, and refreezing, outlining how organizations can effectively implement change. He emphasized the importance of understanding the social context in which behavior occurs and is often considered the father of modern change management. His work laid the foundation for many contemporary theories in psychology, education, and organizational leadership.
