LeShan holds a Ph.D. in Human Development from the University of Chicago and has taught at Pace College, Roosevelt University, and the New School for Social Research. He worked as a clinical and research psychologist for more than 50 years, including six years as a psychologist in the U.S. Army.
In the 1960s and 1970s, LeShan conducted extensive research in the field of parapsychology. In his book The Medium, the Mystic, and the Physicist: Toward a General Theory of the Paranormal, he investigated paranormal topics, mystical thought and quantum mechanics. In the book LeShan claimed to have tested his hypothesis of “clairvoyant reality”. He said the results were a success and he could heal with mental power and train others to do the same.
In World of the Paranormal: The Next Frontier, LeShan advanced his paranormal ideas further, claiming that psychic abilities such as clairvoyance, precognition and telepathy can be explained using quantum theory.
In the 1980s, LeShan’s focus shifted to the psychotherapy of cancer support, a field in which he is considered a pioneer. LeShan lives in New York City. LeShan was married to the late Eda LeShan, who was also a writer.
