Editor's Take:

Aleister Crowley spent his inherited fortune on poetry, mountaineering and magic, and became a byword for scandal. He claimed The Book of the Law was dictated to him by a spirit during a stay in Cairo. Its teaching that people should follow their true will became the basis of Thelema. His commune in Sicily drew lurid press stories and ended with his expulsion. He died poor in Hastings in 1947. Later decades brought fresh interest. Rock musicians and the 1960s counterculture treated him as an icon of rebellion.
