J. G. Pratt

Born in 1910 and died in 1979, J. G. Pratt was an American psychologist best known for his long association with J. B. Rhine's Parapsychology Laboratory at Duke University. His research focused on subjects such as extrasensory perception, psychokinesis, mediumship, and poltergeists, making him one of the notable figures in twentieth-century parapsychology.

Over the course of his career, he worked for many years at Duke and later was associated with the University of Virginia. He also co-authored Parapsychology: Frontier Science of the Mind, a book that introduced readers to the methods and aims of parapsychological research.

Whatever readers make of the field itself, his career offers a window into a period when researchers were trying to test unusual claims with formal experiments and careful observation.
