An examination of personality and attitudinal characteristics of students who participated in the Free Speech Movement (FSM) at the University of California (Berkeley) in Fall 1964. Research data reveal the FSM activists to be well-qualified students with good to excellent academic records, diverse intellectual interests, strong motivations toward knowledge, and deep commitments to university, social and political problems. When compared to non-participating students, FSM participants were found to be an atypical minority that behaved with considerable independence and autonomy to the point of public protest activities even at the risk of arrest. Individual differences and attitudes are discussed with emphasis placed on characteristics as they relate to future activities and continuing commitments. This student group seems to possess a variety of qualities and attributes generally indicative of potential greatness. (WM)
