The Procter Prize recipient receives a $5,000 honorarium and designates a younger colleague, usually in the same field of research, to receive a $5,000 Grant in Aid of Research.

William Procter


William Procter (1872-1951), was the grandson and heir of one of the founders of the Procter and Gamble Company. After graduating from Phillips Exeter, Procter majored in chemistry at Yale, obtaining a Ph.D. in 1894 from the Sheffield Scientific School. He organized the investment firm of Procter and Borden in 1902, retiring from it in 1920, though he continued to serve on the board of directors of Procter and Gamble.

During his boyhood summers at Newton, Connecticut, he became interested in insects. At age forty-five he enrolled in the department of zoology at Columbia University where he was elected to Sigma Xi in 1939).

In 1928, he built a field laboratory on Mt. Desert Island, Maine and began publishing a series of surveys that gained him a reputation as a distinguished natural scientist.

In addition to his active support of Sigma Xi and its affiliated organization, the Research Society of America (RESA), Procter was connected with the Academy of Natural Sciences of Philadelphia, Plymouth Marine Laboratory (England), the American Museum of Natural History, the New York Entomological Society, the Royal Academy of Science of Canada and the London Ray Society.

Procter endowed the award that bears his name in 1950, the year before he died. Karl T. Compton, then Massachusetts Institute of Technology president and RESA chairman, was its first recipient. RESA merged with Sigma Xi in 1974.
