Edgar Cayce (/ˈkeɪsiː/; March 18, 1877 – January 3, 1945) was an American clairvoyant who reported and chronicled an ability to diagnose diseases and recommend treatments for ailments while asleep. During thousands of transcribed sessions, Cayce would answer questions on a variety of subjects, such as healing, reincarnation, dreams, the afterlife, past lives, nutrition, Atlantis, and future events. Cayce described himself as a devout Christian and denied being a Spiritualist or communicating with spirits. Cayce is regarded as a founder of the New Age movement and a principal source of many of the movement's characteristic beliefs.
As a clairvoyant, Cayce collaborated with a variety of individuals, including osteopath Al Layne, homeopath Wesley Ketchum, printer Arthur Lammers, and Wall Street broker Morton Blumenthal. In 1931, Cayce founded a non-profit organization, the Association for Research and Enlightenment. In 1942, a popular and highly sympathetic biography of Cayce titled There is a River was published by journalist Thomas Sugrue.
