Charles T. Tart (April 29, 1937 – March 5, 2025) was a pioneering American psychologist and parapsychologist renowned for his groundbreaking work on consciousness, especially altered states and psi phenomena. Born in Morrisville, Pennsylvania, and active as a teenage radio engineer, Tart shifted from MIT to Duke to explore parapsychology under J.B. Rhine, later earning a Ph.D. from UNC Chapel Hill in 1963 and completing postdoctoral hypnosis research at Stanford. Over a 28‑year academic career at UC Davis and roles at multiple institutes, he authored key texts—Altered States of Consciousness (1969) and Transpersonal Psychologies (1975)—helping establish transpersonal psychology.
