History:
Wikipedia: "In 1925 Western Electric Research Laboratories and part of the engineering department of the American Telephone & Telegraph company (AT&T) were consolidated to form Bell Telephone Laboratories, Inc., as a separate entity. The first president of research was Frank B. Jewett, who stayed there until 1940. The ownership of Bell Laboratories was evenly split between AT&T and the Western Electric Company. Its principal work was to design and support the equipment that Western Electric built for Bell System operating companies, including telephone exchange switches. Support work for the phone companies included the writing and maintaining of the Bell System Practices (BSP), a comprehensive series of technical manuals. Bell Labs also carried out consulting work for the Bell Telephone Companies, and U.S. government work, including Project Nike and the Apollo program. A few workers were assigned to basic research, and this attracted much attention, especially since they produced several Nobel Prize winners. Until the 1940s, the laboratory's principal locations were in and around the Bell Labs Building in New York City, but many of these were moved to the New York suburbs area of New Jersey. Among the later Bell Laboratories locations in New Jersey were Murray Hill, Holmdel, New Jersey, Crawford Hill, New Jersey, the Deal Test Site, Freehold, New Jersey, Lincroft, Long Branch, Middletown, Princeton, Piscataway, Red Bank, and Whippany, New Jersey. Of these, Crawford Hill, and Whippany remain in existence. The largest grouping of people in the company was in Illinois, at Naperville-Lisle, in the Chicago area, which had the largest concentration of employees (about 11,000) prior to 2001. There also were groups of employees in Columbus, Ohio, North Andover, Massachusetts, Allentown, Pennsylvania, Reading, Pennsylvania, and Breinigsville, Pennsylvania, and Westminster, Colorado. Since 2001, many of the former locations have been scaled down, or shut down entirely. At its peak, Bell Laboratories was the premier facility of its type, developing a wide range of revolutionary technologies, including radio astronomy, the transistor, the laser, information theory, the UNIX operating system, and the C programming language. There have been seven Nobel Prizes awarded for work completed at Bell Laboratories."
