Thornton C. Fry received his bachelor's degree from Findlay College in 1912 and then pursued graduate study in Wisconsin in mathematics, physics, and astronomy. He received his M.A. in 1913 and his Ph.D. in 1920 in applied mathematics from the University of Wisconsin-Madison with thesis under the supervision of Charles S. Slichter.
Fry was employed as an industrial mathematician by Western Electric Company from 1916 to 1924 and then by Bell Telephone Laboratories, which was half-owned by Western Electric. He headed a corporate division for industrial applications of mathematics and statistics and was involved in research and development for the U.S. federal government in both world wars.

He would subsequently be appointed as Vice-President head of the UNIVAC Division over Norris in April 1957. After retiring from Sperry-Rand in 1961 he worked as a consultant with Boeing Scientific Research Labs and also, during the 1960s, with Walter Orr Roberts, director of the National Center for Atmospheric Research.
In 1924 Fry was an Invited Speaker of the International Congress of Mathematicians in Toronto. In 1982 the Mathematical Association of America gave him the MAA's distinguished service award.
