Phineas Parkhurst Quimby (1802-1866) was a New England mesmerist, teacher, and mental healer who lived in Belfast, Maine. He developed an original healing philosophy related to mesmerism and Swedenborgianism which essentially was "a belief system that included the tenet that illness originated in the mind as a consequence of erroneous beliefs and that a mind open to God's wisdom could overcome any illness." Upon his death Quimby left behind only loosely organized and unpublished manuscripts which were later publicized by his patient-disciples, especially Annetta Seabury Dresser, Julius Dresser, and Warren Felt Evans, who developed Quimby's teachings into the New Thought or Mind Cure philosophy. A fourth disciple, Mary Baker Eddy, transformed her interpretation of the Quimby manuscripts into the basis for the Church of Christ, Scientist. Quimby is thought by some to have been the first secular psychotherapist to practice in the United States. Source: Robert C. Fuller.
