Vivianne Crowley is an author, university lecturer, psychologist, and High Priestess and teacher of Wicca. She was initiated into the London coven of Alex Sanders (founder of the Alexandrian tradition of Wicca) at the age of eighteen, but later joined a Gardnerian coven of the Whitecroft lineage derived from Eleanor Bone, and so she was one of few people in the seventies to be part of both Traditions.
