Marie Ann, Alma and Leah Hirsig were sisters with a shared interest in gurus. Born in Switzerland, the family moved to New York City when Leah was 2 years old. In 1918 Alma introduced Leah to Aleister Crowley who was living in Greenwich Village at the time. Soon Leah would become Crowley’s Scarlet Woman and co-founded the Abbey of Thelema in Cefalu, Sicily with him. (more on Leah The Order of the Eagle site: http://hermetic.com/sabazius/hirsig.htm
