EG&G, formally known as Edgerton, Germeshausen, and Grier, Inc.; in Boston, Massuchusetts, is 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.

In 1931 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 Grier in 1934. Bernard O'Keefe became the fourth member of the technology group. The group's high-speed photography was used to image tests during the war. After the war the group continued and formally incorporated Edgerton, Germeshausen, and Grier, Inc. in 1947.

Founded: 1931
Production: 1947 - 2009
1950s and 1960s During the 1950s and 1960s, EG&G was involved as a major contractor for the United States Atomic Energy Commission. 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 used to detect 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 and security systems.
1970s to the Present 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. purchased the Analytical Instruments Division of PerkinElmer for US$425 million, also assuming the PerkinElmer name. At the time EG&G was based in Wellesley, Massachusetts, and made products for diverse industries including automotive, medical, aerospace and photography. From 1999 until 2001 EG&G was wholly owned by The Carlyle Group. In August 2002, the defense and services sector of the company was acquired by defense technical services giant URS Corporation. URS' EG&G division is headquartered in Gaithersburg, Maryland and employs over 11,000 people. At its peak in the 1980s EG&G had some 35,000 employees. In December 2009 URS announced its decision to discontinue the use of "EG&G" as a division name.
