Undated photograph of Leary staring at artwork, Timothy Francis Leary (October 22, 1920 - May 31, 1996) was an 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"; "set and setting"; and "think for yourself and question authority". He wrote and spoke frequently about trans-humanist concepts involving space migration, intelligence increase and life extension, and developed the eight-circuit model of consciousness in his book Exo-Psychology (1977). During the 1960s and 1970s, he was arrested often enough to see the inside of 29 different prisons worldwide. He died of prostate cancer in1996 at the age of 75. Seven grams of Leary's ashes were arranged by his friend at Celestis to be buried in space aboard a rocket carrying the remains of 24 others including Gene Roddenberry (creator of Star Trek), Gerard O'Neill (space physicist), and Krafft Ehricke (rocket scientist). A Pegasus rocket containing their remains was launched on April 21, 1997, and remained in orbit for six years until it burned up in the atmosphere.
