Timothy Francis Leary, Jr. (1920-1996), a psychologist and writer, became known as an advocate for the use of psychedelic drugs and a counterculture icon. The Timothy Leary papers contain records created and accumulated by Leary over his entire life, as well estate records created after his death. The papers comprehensively document his life and activities: as a child, student, professional psychologist, lecturer and researcher at Harvard, unaffiliated psychedelic guru, prisoner, escapee, exile, and futurist.
