Background
- Scope and content:
-
The George R. Trimble Jr. collection contains technical papers, conference proceedings, and manuals from Trimble's work at institutions including the Ballistic Research Laboratory and Computer Usage Company, as well as records from Trimble's projects as an independent consultant. The majority of the collection's independent consulting reports relate to the Mergenthaler 5500 System and also personal rapid transit system projects for the Urban Mass Transportation Administration. A significant amount of the technical papers and conference proceedings in this collection were authored by Trimble and relate to his work at BRL, CUC, and Penta Computer Associates, though writings by others are also included. Small amounts of promotional materials and catalogs are interfiled with technical papers and manuals when they are related to the same programs and products. The collection spans 1948 through 2000 with the bulk of the collection being from 1955 to 1975 during Trimble's years at CUC, Penta Computer Associates, and as an independent consultant.
- Biographical / historical:
-
George R. Trimble Jr. was born April 26, 1929, in Elkton, Maryland. He received his BA from St. John's College in Annapolis, Maryland, in 1948, and his master's degree in mathematics from the University of Delaware in Newark in 1952.
In 1948, Trimble began working at the Computing Laboratory of the Ballistic Research 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 software development company as corporate technical director of systems programming. While at CUC, he supervised major application programs and was involved in most of the company's projects, including heading the design of a computer-based air traffic control system for the Federal Aviation Administration and the development of software and an operating system for the Texas Instruments Advanced Scientific Computer.
In 1968, Trimble left CUC and went to Penta Computer Associates as the vice president of research and development. At Penta, he worked on the design and development of applications, mainly real-time and systems programming, and conceived and developed Penta's KeyLogic data entry system. Trimble left Penta in 1971 after it was acquired by REDCOR and began working as an independent consultant with his own business, T-Logic. Projects Trimble worked on as a consultant include the design of personal rapid transit systems for the U.S. Department of Transportation's Urban Mass Transportation Administration and the creation of software for companies like Mergenthaler Linotype Company and Lockheed Electronics Company, among others. Trimble also led seminars and talks on computing around the world. He died March 13, 2007.
