Laboratories at Aberdeen Proving Ground in Aberdeen, Maryland, where he contributed to the
programming and development of the ENIAC, EDVAC, ORDVAC computers as well Bell
Laboratories and International Business Machine’s (IBM) relay calculators. He joined IBM’s
research labs in Endicott, New York, in 1952 and worked as a senior staff member of the
Applied Science Division where he helped design many of IBM’s early computers, including the
650 and 700 series systems, and wrote one of the first commercially available software
programs for the 650.
Trimble moved on to Computer Usage Company (CUC) in 1956, spending 12 years at the
