Aleister Crowley (Oct. 12, 1875-Dec. 1, 1947) — however one judges him — was a fascinating man who lived an amazing life. He is best known as being an infamous occultist and the scribe of The Book of the Law, which introduced Thelema to the world. Crowley was an influential member in several occult organizations, including the Golden Dawn, the A.'.A.'., and Ordo Templi Orientis. He was a prolific writer and poet, a world traveler, mountaineer, chess master, artist, yogi, social provocateur, drug addict and sexual libertine. The press loved to demonize him and dubbed Crowley “The wickedest man in the world."
