EG&G, formally known as Edgerton, Germeshausen, and Grier, Inc., was a United States national defense contractor and provider of management and technical services. The company was involved in contracting services to the United States government during World War II and conducted weapons research and development during the Cold war era (from 1948 and onward). It had close involvement with some of the government's most sensitive technologies. History Early history In 1931, Massachusetts Institute of Technology (MIT) professor Harold Edgerton, a pioneer of high-speed photography, partnered with his graduate student Kenneth Germeshausen to found a small technical consulting firm. The two were joined by fellow MIT graduate student Herbert E. Grier in 1934. Bernard "Barney" O'Keefe became the fourth member of their fledgling technology group. The group's high-speed photography was used to image implosion tests during the Manhattan Project. The same skills in precisely timed high-power electrical pulses also formed a key enabling technology for nuclear weapon triggers. After the war, the group continued their association with the burgeoning military nuclear effort and formally incorporated Edgerton, Germeshausen, and Grier, Inc. in 1947. 1950s and 1960s During the 1950s and 1960s, EG&G was involved in nuclear tests as a major contractor for the Atomic Energy Commission. EG&G made extensive use of the Nevada Test Site (NTS) for weapons development and high-technology military testing at Nellis AFB. EG&G has shared operations responsibility for the NTS with Livermore Labs, Raytheon Services Nevada, Reynolds Electrical and Engineering (REECO) and others. Subsequently, EG&G expanded its range of services, providing facilities management, technical services, security, and pilot training for the U.S. military and other government departments. EG&G builds a variety of sensing, detection and imaging products including night vision equipment, sensors for detection of nuclear material and chemical and biological weapons agents, and a variety of acoustic sensors. The company also supplies microwave and electronic components to the government, security systems, and systems for electronic warfare and mine countermeasures. 1970s and 1980s During the 1970s and 1980s, the company, then led by O'Keefe, diversified by acquisition into the fields of paper making, instrumentation for scientific, marine, environmental and geophysical users, automotive testing, fans and blowers, frequency control devices and other components including BBD and CCD technology via their Reticon division. In the late 1980s and early 1990s most of these divisions were sold, and on 28 May 1999, the non-government side of EG&G Inc.; formerly ; purchased
