Aleister Crowley (1875-1947) was the most widely read author in 20th-century occultism. He single-handedly redefined magic as a field of inquiry and endeavor through his books and the order that he led—the A.A. and the O.T.O. He is the author of 777 & Other Qabalistic Writings, Book of Toth, and The Book of the Law.
