Psychologist Timothy Leary is the father of the psychedelic movement of the 1960s and its experiments with mind-altering drugs. In 1960, Leary joined the faculty of Harvard at the Center for Personality Research, where he analyzed the effects of psychedelics and personality. As part of his research, introduced L.S.D. and other psychedelic drugs to many, and also used them himself. Leary was eventually asked to leave the university, and later served time in jail on drug charges. After his release, Leary went a tour debating one of his nemeses, G. Gordon Liddy.
