There is nothing so practical as a good theory.
Who they were
Kurt Lewin treated behavior as the product of a person and their environment together, mapping the psychological field of forces — the life space — in which choices actually unfold. He turned abstract theory into experiment, studying how groups make decisions, resolve conflict, and change, and his unfreeze, change, refreeze model still shapes how organizations think about transformation. He brought rigor and humanity in equal measure to the study of prejudice, leadership, and group life. His conviction that there is nothing so practical as a good theory guided generations of researchers.

Field Theory
Kurt Lewin proposed that behavior is the product of the whole situation a person is in at that moment, the balance of forces pushing and pulling within their psychological field. Change happens by easing the forces that hold us in place rather than simply pressing harder for something new.
