The Brown Instrument Company developed, manufactured, and sold industrial controls and measuring instruments, such as thermometers, pressure gauges, voltmeters, and pyrometers. The company was founded in 1857 by an English engineer and inventor, Edward Brown (1834-1905). The records of the Brown Instrument Company consist of research files documenting the development of measuring instruments and industrial control systems used in continuous process manufacturing.

The Engineering Dept. reports document the work of the department, primarily in the applications of analog computers. Important projects include: automatic pilots, computerized flight systems, instrument controls for nuclear submarines, space satellite technology, and internal guidance systems for long-range and medium-range missiles, including the Nike-Zeus.

Isaac Auerbach (1921-1992) joined the staff of the Eckert-Mauchly Computer Corporation to work on the UNIVAC project in June of 1946. One of his initial assignments was to survey and analyze the "large-scale computing projects" that were underway in the various computational laboratories throughout the country. This report goes through the history of analog computing, the development of digital computing and computational theory, current computer development projects at research institutions and commercial firms, and the commercial market for electronic digital computers.
