Woodruff, Joseph L(eroy) (1913-1988)

Professor of psychology active in the field of parapsychology. He was born October 8, 1913, in Galesburg, Illinois. He studied at Tarkio College, Missouri (B.A., 1936) and Duke University (M.A., 1939; Ph.D., 1941). While at Duke, Woodruff, in conjunction with Joseph G. Pratt, conducted one of the most famous ESP tests, still generally considered one of the best ever carried out in parapsychology.

In 1946 he began a lengthy tenure teaching psychology at the City College of New York. For some years Woodruff conducted quantitative research in extrasensory perception, with particular reference to the relationship between certain subjective aspects of card-calling and success in calling. In 1959 he became the secretary of the board of trustees of the American Society for Psychical Research. He was also a charter member of the Parapsychological Association. He died July 23, 1988.
