Ian Pretyman Stevenson (October 31, 1918 – February 8, 2007) was a Canadian-born U.S. psychiatrist. He worked for the University of Virginia School of Medicine for fifty years, as chair of the department of psychiatry from 1957 to 1967, Carlson Professor of Psychiatry from 1967 to 2001, and Research Professor of Psychiatry from 2002 until his death.
As founder and director of the university's Division of Perceptual Studies, which investigates the paranormal, Stevenson became known internationally for his research into reincarnation, the idea that emotions, memories, and even physical injuries in the form of birthmarks, can be transferred from one life to another. He traveled extensively over a period of forty years, investigating three thousand cases of children around the world who claimed to remember past lives. His position was that certain phobias, philias, unusual abilities and illnesses could not be fully explained by heredity or the environment. He believed that reincarnation provided a third type of explanation.
Ian Stevenson was for many years Chairman of the Department of Psychiatry at the University of Virginia, and he was a leading researcher in the field of reincarnation. Stevenson spent a half-century studying cases of young children who remembered recent previous lives that had ended violently, and the result is a spectacular body of work which will be celebrated only when the rest of modern science catches up with it. Stevenson wrote for scientists, so his writing style is dry. But the work that he details in his dozen or more volumes is overwhelming evidence for immediate reincarnation in what appears to be the narrow case of unexpected violent death. These are three of his seminal works.
