Obituary: Ivan Steiner (1917-2001).

I. D. Steiner died in Arden, North Carolina, on December 1, 2001, at the age of 84--and social psychology lost one of its major theorists and researchers. Although Steiner's broad conceptual interests led him to write on a variety of theoretical topics throughout his career--for example, interpersonal behavior, and social perception, authoritarianism, perceived freedom, responses to inconsistency, the attribution of choice, heuristic models of groupthink--small-group performance remained his principle focus and the primary engine of his fame.
