Question: Who died at an earlier date, H. P. Lovecraft or Timothy Leary?
Context: The Harvard Psilocybin Project was a series of experiments in psychology conducted by Dr. Timothy Leary and Dr. Richard Alpert.  The founding board of the project consisted of Leary, Aldous Huxley, David McClelland (Leary's superior at Harvard University), Frank Barron, Ralph Metzner, and two graduate students who were working on a project with mescaline.  The experiments began some time in 1960 and lasted until March 1962, when other professors in the Harvard Center for Research in Personality raised concerns about the legitimacy and safety of the experiments in an internal meeting. Leary v. United States, 395 U.S. 6 (1969) , is a U.S. Supreme Court case dealing with the constitutionality of the Marihuana Tax Act of 1937.  Timothy Leary, a professor and activist, was arrested for the possession of marijuana in violation of the Marihuana Tax Act.  Leary challenged the act on the ground that the act required self-incrimination, which violated the Fifth Amendment.  The unanimous opinion of the court was penned by Justice John Marshall Harlan II and declared the Marihuana Tax Act unconstitutional.  Thus, Leary's conviction was overturned.  Congress responded shortly thereafter by replacing the Marihuana Tax Act with the newly written Controlled Substances Act while continuing the prohibition of certain drugs in the United States. Timothy Francis Leary (October 22, 1920 – May 31, 1996) was an American psychologist and writer known for advocating the exploration of the therapeutic potential of psychedelic drugs under controlled conditions.  Leary conducted experiments under the Harvard Psilocybin Project during American legality of LSD and psilocybin, resulting in the Concord Prison Experiment and the Marsh Chapel Experiment.  Leary's colleague, Richard Alpert (Ram Dass), was fired from Harvard University on May 27, 1963 for giving psilocybin to an undergraduate student.  Leary was planning to leave Harvard when his teaching contract expired in June, the following month.  He was fired, for "failure to keep classroom appointments", with his pay docked on April 30.  National illumination as to the effects of psychedelics did not occur until after the Harvard scandal. The League for Spiritual Discovery was a spiritual organization inspired by the works of Timothy Leary, and strove for legal use of lysergic acid diethylamide (LSD) for the purpose of meditation, insight, and spiritual understanding.  It was in existence during the mid-to-late 1960s, and eventually closed by Leary.  The New York Center for the League of Spiritual Discovery, in existence for around a year, was co-founded by Timothy Leary and Nina Graboi in 1966.  The center was the first LSD-based meditation center in Manhattan. You Can Be Anyone This Time Around is an album by Timothy Leary released in 1970.  The disc features three "raps" by Leary backed with psychedelic music.  The purpose of the album was to raise funds for Leary's political candidacy for Governor of California. H. P. Lovecraft is the debut album by the American psychedelic rock band H. P. Lovecraft and was released in October 1967 by Philips Records.  It blended psychedelic and folk rock influences and was marked by the haunting, eerie ambiance of the band's music, which itself was often inspired by the literary works of horror writer H. P. Lovecraft, after whom the band had named themselves.  Although most of the album comprises interpretations of traditional and contemporary folk songs, it also features the self-penned compositions "That's How Much I Love You, Baby (More or Less)", "The Time Machine", and arguably the band's best known song, "The White Ship".  The traditional song "Wayfaring Stranger" was released as a single just ahead of the album in September 1967 and "The White Ship" was issued shortly after the album appeared, although neither single reached the charts.  Like its attendant singles, "H. P. Lovecraft" was also somewhat commercially unsuccessful and failed to reach the "Billboard" Top LPs chart or the UK Albums Chart, although it did sell reasonably well over time. Howard Phillips Lovecraft ( ; August 20, 1890 – March 15, 1937) was an American author who achieved posthumous fame through his influential works of horror fiction.  He was virtually unknown and published only in pulp magazines before he died in poverty, but he is now regarded as one of the most significant 20th-century authors in his genre.  Lovecraft was born in Providence, Rhode Island, where he spent most of his life.  Among his most celebrated tales are "The Call of Cthulhu" and "The Shadow over Innsmouth", both canonical to the Cthulhu Mythos.  Lovecraft was never able to support himself from earnings as author and editor.  He saw commercial success increasingly elude him in this latter period, partly because he lacked the confidence and drive to promote himself.  He subsisted in progressively strained circumstances in his last years; an inheritance was completely spent by the time that he died at age 46. "Turn on, tune in, drop out" is a counterculture-era phrase popularized by Timothy Leary in 1966.  In 1967 Leary spoke at the Human Be-In, a gathering of 30,000 hippies in Golden Gate Park in San Francisco and phrased the famous words, "Turn on, tune in, drop out".  It was also the title of his spoken word album "Turn On, Tune In, Drop Out" recorded in 1966.  On this lengthy album one can hear Leary speaking in a monotone, soft-spoken voice on his views about the world and humanity and describing nature, Indian symbols, "the meaning of inner life", the LSD experience, peace and many other issues. "The White Ship" is a song released by the American psychedelic rock band, H. P. Lovecraft, in November 1967.  The songwriting is credited to band members George Edwards, Dave Michaels, and Tony Cavallari.  Acting as the opening song on the second side of their debut LP, "H. P. Lovecraft", it was the album's longest track, and an edited version was also released as the band's second single.  The name and theme of the song derive directly from author H. P. Lovecraft's short story, "The White Ship".  Despite its failure to chart nationally, it is widely considered to be H. P. Lovecraft's most accomplished piece, and helped establish the group, who were originally from Chicago, in the West Coast music scene.
