Aleister Crowley - The Master Of Darkness

Aleister Crowley, born Edward Alexander Crowley, (12 October 1875 – 1 December 1947; the surname is pronounced /'krəʊ.li/ i.e. with the first syllable sounding like "crow" in English) was a British occultist, writer and mystic.

He is perhaps best known today for his occult writings, especially The Book of the Law, the central sacred text of Thelema. Crowley was also an influential member in several occult organizations, including the Golden Dawn, the Argenteum Astrum, and Ordo Templi Orientis (O.T.O.).

Other interests and accomplishments were wide-ranging—he was a chess player, mountain climber, poet, painter, astrologer, hedonist, drug experimenter, and social critic.

Crowley himself claimed to be a Freemason, but the regularity of his initiations with the United Grand Lodge of England has been disputed.

Crowley gained much notoriety during his lifetime, and was famously dubbed "The Wickedest Man In the World."
