Leon Festinger was a pioneering psychologist who developed the theory of cognitive dissonance.
Born in New York, he earned degrees from City College of New York and Iowa State University.
Festinger's work at Stanford University in the 1950s led to the formulation of cognitive dissonance theory, which explores how people reconcile conflicting beliefs and behaviors.
This influential concept sparked extensive research in social psychology.
Festinger later taught at the New School for Social Research and was active in professional organizations.
He continued his research until his death in 1989, leaving a lasting impact on the field of psychology.
