Born 22 Oct 1920; died 31 May 1996.
American writer and psychologist most famous for his advocacy of the therapeutic and spiritual benefits of LSD. His most significant recording was the 1967 album Turn On, Tune In, Drop Out (a phrase coined by Dr Leary) - ostensibly a "user manual" for a self-guided LSD trip.

After his death in 1996, he was cremated, and his remains were distributed amongst his friends and family. On 21 April 1997, seven grams of the ashes were shot into space contained in a rocket, along with the ashes of other notable individuals. It remained in orbit for six years, at which point it burned up into the atmosphere.
