1.  Aleister Crowley (1875-1947) was the foremost ceremonial magician of the first half of the 20th century. He was born in Leamington, England, on October 12, 1875, the son of fanatical Plymouth Brethren. His mother called him the Beast of Revelation, whose number is 666, and Crowley embraced this identification. He attended Cambridge and began to study occultism. He was an accomplished chess player, mountain climber, and poet. In 1898, he joined the Hermetic Order of the Golden Dawn. In 1903, he married Rose Kelly. In 1904, while on an extended honeymoon with Rose in Cairo, he received The Book of the Law from a "praeternatural" entity calling himself Aiwass. This book identified Crowley as the Logos of a New Aeon, and Crowley spent the rest of his life trying to spread the new religion. He died in a rooming house in Hastings on December 1, 1947.
