Edgar Cayce (/ˈkeɪsiː/; March 18, 1877 – January 3, 1945) was an American mystic who answered questions on subjects as varied as healing, reincarnation, wars, Atlantis, and future events while in a trance. A biographer gave him the nickname, "The Sleeping Prophet." A nonprofit organization, the Association for Research and Enlightenment, was founded to facilitate the study of Cayce's work. A hospital and a university were also established.
