Leary giving a lecture on his first book, Interpersonal Diagnosis of Personality, circa 1950's. Timothy Francis Leary (1920-1996), American psychologist and writer, known for his advocacy of psychedelic drugs. During a time when drugs such as LSD and psilocybin were legal, Leary conducted experiments at Harvard University under the Harvard Psilocybin Project, resulting in the Concord Prison Experiment and the Marsh Chapel Experiment. Both studies produced useful data, but Leary and his associate Richard Alpert were fired from the university because of the public controversy surrounding their research. Leary believed LSD showed therapeutic potential for use in psychiatry. He popularized catchphrases that promoted his philosophy such as turn on, tune in, drop out. |
