Seymour was a renaissance man: widely read in not only psychology but also anthropology, sociology, philosophy, economics, political science, and most especially history. Seymour taught the author the value of being historically informed, which has been an invaluable tool ever since. Seymour had a way of conceptualizing and reformulating whatever issue was brought up so that the author began to see the world differently. Seymour devoted his life to teaching, listening to others, and helping to solve social problems. He used psychological concepts and insights to contribute to the larger debates about encouraging positive societal change. He helped to move educational policy in the direction of focusing on teachers and the school context, to alter policies that treated retarded citizens as needing confinement in total institutions, and to advocate for the underserved, the impoverished, and others who had few or no advocates. Seymour's contributions to the field of community psychology are highlighted.
