Scientology founder L. Ron Hubbard claimed to have had a near-death experience in 1938 that inspired him to write Excalibur, an unpublished manuscript based on the revelations from the experience. In 1945-46, Hubbard was briefly involved with Jack Parsons, an American Thelemite and member of the Agape Lodge of Aleister Crowley's magical order, Ordo Templi Orientis, in Pasadena, California.[1] In 1950, he published Dianetics: The Modern Science of Mental Health, and in 1953 he organized the Church of Scientology.
