Professor Janusz Łukasz Grzelak (1941–2025): social psychologist, professor at the University of Warsaw, democratic opposition activist, civic leader

Abstract

Janusz Grzelak (1941–2025) was a distinguished social psychologist whose pioneering research on social interdependence and conflict resolution made a lasting impact on both Polish and global social psychology. Equally significant was his dedication to civic and democratic causes. As a representative of Solidarity during the historic Round Table talks, he played a vital role in shaping Poland’s democratic transition. In the years that followed, he remained deeply engaged in civic initiatives at both national and local levels. We honor his memory and lasting legacy.
