Professor Ian Stevenson, who died on February 8 aged 88, was the world's foremost scientific authority on the study of reincarnation. The founder and director of the Division of Personality Studies at the University of Virginia, Stevenson spent more than 40 years travelling the world, accumulating more than 3,000 cases of children who appeared to have memories of previous lives. Stevenson's studies were informed by an encyclopaedic knowledge of history, philosophy and the natural sciences but characterised above all by an empirical rigour. He would travel vast distances to interview the children and their current and previous" families, meticulously noting corroborative and conflicting statements in their accounts, and cross-checking official records, and police and autopsy reports. In 1960 he published his first paper on the subject ... which caught the attention of Chester Carlson, the inventor of the Xerox machine. In 1963 Carlson collapsed in a cinema and died. When his will was read, Stevenson was astonished to learn that Carlson had left $1 million to endow a chair at the University of Virginia, and a further $1 million for Stevenson himself to continue his researches into reincarnation. Carlson's bequest enabled Stevenson to set up the Division of Personality Studies, the only academic department in the world dedicated to the study of previous life memories, near-death experiences and other paranormal phenomena.
