"Founded in the 1930s by Dr. Arnold O. Beckman, Beckman Instruments first marketed analytical apparatus to chemical laboratories. In 1955, Beckman hired William Shockley, co-inventor of the transistor, to head up its new semiconductor division in Mountain View, California. The following year, Shockley won the Nobel Prize and began personally recruiting top researchers in the country to work for him. Although brilliant, Shockley could be erratic managerially and eight of his key employees—whom he later called ‘the traitorous eight,’ left to found Fairchild Semiconductor, the single most important company behind the transformation of the fruit-bearing Valley of Heart's Delight into Silicon Valley the world center of semiconductor and computer research. The Beckman firm took over several other companies and, for a few years in the 1980s, merged with the SmithKline Corporation but eventually became it own entity again. It is now a major multinational corporation in the health care instrumentation field." (Source: Computer History Museum)

"Fisher Scientific International, Inc. was a laboratory supply and biotechnology company that provided products and services to the global scientific research and clinical laboratory markets until its merger with Thermo Electron in 2006, after which it became Thermo Fisher Scientific. The company was founded in Pittsburgh, Pennsylvania, in 1902 by Chester Garfield Fisher (1881–1965), originally called the "Scientific Materials Co." Fisher became a supplier of lab equipment and reagents for the area's industrial research. Early products included microscopes, burets, pipettes, litmus, balances, colorimeters, dissecting kits, and anatomical models. Fisher established an R&D lab at his company in 1915. In 1925, the company purchased Montreal-based Scientific Supplies, Ltd. The same year, the company was renamed Fisher Scientific. In 1940, Fisher Scientific acquired the New York supply company Eimer & Amend. In 1955, Fisher established a chemical manufacturing facility in Fair Lawn, New Jersey. In 1957, the company purchased the New York–based medical apparatus supply company E. Machlett & Sons. In 1959 the company opened an instrument and supplies facility in Indiana, Pennsylvania. In 1968, it purchased Massachusetts-based Jarrell-Ash Company, a producer of optical instrumentation, particularly for emission and atomic absorption spectroscopy. It acquired Chicago-based Stansi Scientific Company in 1967, expanding into educational science supplies. In 1976, Fisher Scientific established an Instrument Service Division. Fisher was acquired by Morristown, New Jersey–based Allied Corporation in 1981. Operating as a subsidiary of Allied Corporation (and later AlliedSignal Inc., and The Henley Group), Fisher established a Biotechnology Division in 1985. In 1991, The Henley Group sold a majority interest in Fisher through a public stock offering. The public entity was called Fisher Scientific International Inc., and based in Hampton, New Hampshire. Fisher Scientific Company remained in Pittsburgh as an operating subsidiary. In the 1990s, Fisher, with partner Intertech Corporation of Atkinson, New Hampshire, set up a pharmaceutical testing and certification lab in Moscow, Russia, to serve with the Russian Federation's Ministry of Health and Medical Industry needs. Fisher acquired Eastman Kodak Company's organic-chemicals business and Janssen Chimica, forming Acros Organics. In August 2004, the company merged with Apogent Technologies Inc. In May 2006, Fisher Scientific and Thermo Electron announced that they would merge in a tax-free, stock-for-stock exchange. The merger closed on November 9, 2006, and the merged company is now called Thermo Fisher Scientific." (Source: Wikipedia)
