House History

Clifford Berry ('38 elec engr), co-inventor of the electronic digital computer. CLIFFORD EDWARD BERRY was born in Gladbrook, Iowa. He received his B.S. in Electrical Engineering in 1939. Professor Harold Anderson was a professor of electrical engineering and John Vincent Atanasoff asked him if he could recommend a graduate student in electrical engineering to assist him in his computing machine project, Professor Anderson immediately thought of Clifford Berry. In December 1939 a demonstration of the prototype to Iowa State College officials convinced them that JVA’s project was worthy of a grant of $850 from the Iowa State College Research Council to construct a full-scale machine capable of solving systems of equations. The following spring, JVA and Berry sent materials and drawings of the ABC to Chicago patent lawyer Richard R. Trexler, who had been hired by Iowa State College to give them advice on how to protect their invention. Berry received his M.S. in Physics in 1941. In 1942, Berry took a job with Consolidated Engineering Corporation in Pasadena, California. Under a special arrangement with Iowa State, he did his research in absentia and completed the requirements for the Ph.D. (in physics) in 1948, while employed by C.E.C. In 1948 he received the doctorate after presenting a thesis titled The Effects of Initial Energies on Mass Spectra. He became Chief Physicist at C.E.C. in 1949 and Assistant Director of Research in 1952. He was made Director of Engineering of the Analytical and Control Division in 1959 and also served as its Technical Director. In early October 1963 he left C.E.C. to become Manager of Advanced Development at the Vacuum-Electronics Corporation in Plainview, New York. He died suddenly on October 30, 1963. Dr. Berry was issued 19 patents in the area of mass spectrometry, 11 patents in various areas of vacuum and electronics and, at the time of his death, had 13 patents pending. He was a member of the American Physical Society, American Vacuum Society, American Association for the Advancement of Science, Sigma Xi, Eta Kappa Nu, Pi Mu Epsilon, and Phi Kappa Phi.
