Summary

German-American psychologist who founded social psychology's experimental tradition by developing field theory — representing behavior as a function of the person and their psychological environment — and pioneered the study of group dynamics.

Core Contribution

Developed field theory in psychology (B = f(P,E) — behavior is a function of person and environment) and founded the experimental study of group dynamics, action research, and organizational change — creating the foundation for modern applied social psychology.

Key Spikes & Highlights

  • Mathematics of Social Space (applied topological concepts to represent psychological environments — using diagrams of life space — making social psychology geometrically tractable in a way that had no precedent)
