Greville, T(homas) N(all) E(den)(1910-1998)

Mathematician who took part in statistical evaluation of experiments on ESP. He was born December 27, 1910, in New York City and studied at the University of the South in Sewanee, Tennessee (B.A., 1930), and the University of Michigan (M.A., 1932; Ph.D., 1933). After graduation Greville became an instructor in mathematics at the University of Michigan (1937-40) and then worked for the United States Bureau of the Census during World War II (1940-46). After the war he spent his career as a mathematician and statistician for various government agencies.

Greville compiled the United States Life Tables and Actuarial Tables 1939-41 (1946), one of several books on statistics. His parapsychological interest was largely in statistical evaluation of ESP experiments, on which he wrote a number of papers. He was a member of the Parapsychological Association and served as statistical editor of the Journal of Parapsychology.
