[email protected]. Morton (Mort) Deutsch had a long life and productive career. I was one of many who had the good fortune to know him and benefit from his advice and contributions. In this tribute, I recount many of these experiences with an emphasis on the substantive contributions that Mort made to my work including a debate that we had on sources of conflict. Always a source of inspiration, Mort pioneered the study of social-psychological aspects of conflict with his original laboratory experiments, theoretical innovations, and practical advice. Never have we needed his proposal on preventing World War Three more than at this difficult moment in international relations (see Wright, Evan, and Deutsch 1962). He was the last of the illustrious band of students of Kurt Lewin, considered by many to be the founders of modern social and organizational psychology; others included Leon Festinger (the theory of cognitive dissonance), Stanley Schachter (the psychology of affiliation), Harold Kelley and John Thibaut (the social psychology of groups), Kurt Back (on the dynamics of group processes), and Roger Barker (founder of ecological psychology). Their collective influence on social psychologyAuthor Manuscript has been monumental.
