Overview
EG&G, formally Edgerton, Germeshausen, and Grier, Inc., was an American technology, defense, and government-services company. Its origins lay in the technical consulting partnership formed in 1931 by Massachusetts Institute of Technology professor Harold Edgerton and his graduate student Kenneth Germeshausen. Herbert E. Grier joined the group in 1934, and Bernard “Barney” O’Keefe became an important early member. The firm’s initial expertise centered on high-speed photography, precision timing, pulsed electrical systems, and specialized instrumentation. The company’s work became closely associated with the United States nuclear-weapons program. During the Manhattan Project in 1945, its high-speed photography and radiography capabilities were used to record implosion experiments. The group’s knowledge of precisely timed, high-power electrical pulses also had relevance to nuclear-weapon triggering systems. The business was formally incorporated as Edgerton, Germeshausen, and Grier, Inc. in 1947 and continued working with the American military and nuclear establishments during the Cold War. During the 1950s and 1960s, EG&G became a major contractor for the U.S. Atomic Energy Commission and, later, the Department of Energy. It supported nuclear testing and research at the Nevada Test Site in cooperation with national laboratories including Lawrence Livermore, Los Alamos, and Sandia. The company also worked on remote sensing at Nevada’s Nellis Air Force Base. Its government work expanded beyond nuclear testing into facilities operation, technical assistance, security, military training, and engineering support. EG&G developed or supplied a broad range of specialized technologies. These included night-vision equipment, nuclear-material detection systems, chemical and biological-agent sensors, acoustic sensors, microwave and electronic components, electronic-warfare systems, security equipment, and mine-countermeasure technologies. Its government business also included support for sensitive aerospace programs, including work associated with Lockheed Martin’s stealth-development activities. Under the leadership of Barney O’Keefe, especially during the 1970s and 1980s, EG&G diversified through acquisitions. Its portfolio extended into scientific, marine, environmental, and geophysical instrumentation; automotive testing; paper-making equipment; fans and blowers; frequency-control devices; and semiconductor-related technologies. Through its Reticon division, the company was associated with bucket-brigade-device and charge-coupled-device technologies. EG&G also operated an analytical-instruments business and, through EG&G Biomolecular, produced the Acugen 402 automated DNA sequencer, which used slab-gel electrophoresis and radioactive Sanger sequencing. By the late 1980s and early 1990s, many of the diversified commercial divisions had been sold. In 1999, EG&G’s non-government operations acquired PerkinElmer’s Analytical Instruments Division for $425 million and adopted the PerkinElmer name. From 1999 to 2001, EG&G was wholly owned by The Carlyle Group. In August 2002, the defense and government-services portion was acquired by URS Corporation and operated as the URS EG&G division, headquartered in Gaithersburg, Maryland, with more than 11,000 employees. EG&G had employed roughly 35,000 people at its 1980s peak, according to the referenced historical account. URS announced in December 2009 that it would retire the EG&G name and logo, along with other secondary brands, in favor of a unified URS identity. The EG&G division became URS Federal Services. URS was acquired by AECOM in 2014. In 2020, AECOM sold its Management Services division to American Securities and Lindsay Goldberg; the resulting company was named Amentum. Consequently, EG&G no longer operates as an independent corporate brand, although portions of its government-services heritage continued through successor organizations. EG&G was also associated with the Janet airline operation, which transported personnel to restricted government facilities in Nevada and California from a terminal at McCarran International Airport in Las Vegas. In 2000, EG&G and Raytheon Technical Services formed JT3 LLC to support a U.S. Air Force range-technical-services contract; the operation was later associated with JT4 LLC. EG&G’s historical importance rests on the combination of advanced measurement technology, nuclear-test support, classified aerospace work, and long-term federal operations and maintenance contracting.
History
EG&G began in 1931 as a technical consulting partnership between MIT professor Harold Edgerton and Kenneth Germeshausen. Their work focused on high-speed photography, precision timing, and electrical instrumentation. Herbert E. Grier joined in 1934, while Bernard O'Keefe became another important early participant. The group formally incorporated as Edgerton, Germeshausen, and Grier, Inc. in 1947. The firm’s early technical capabilities brought it into the Manhattan Project. In 1945, its high-speed photographic and radiographic methods were used to document implosion experiments. Its expertise in precisely timed electrical pulses also supported the broader technical requirements of nuclear weapons. After World War II, EG&G maintained close relationships with the U.S. government’s nuclear establishment. During the 1950s and 1960s, EG&G served as a prime contractor for the Atomic Energy Commission and later the Department of Energy. It helped manage and operate the Nevada Test Site while working with Lawrence Livermore, Los Alamos, and Sandia laboratories. The company also supported remote sensing at Nellis Air Force Base. Over time, its government portfolio grew to encompass facilities management, security, military training, engineering, and technical assistance. EG&G’s technology businesses produced specialized imaging, sensing, and detection equipment. Its activities included night vision, nuclear-material detection, chemical and biological threat sensing, acoustic systems, microwave components, electronic warfare, and mine countermeasures. The company also supported sensitive aerospace programs, including work connected with stealth development associated with Lockheed Martin. During the 1970s and 1980s, EG&G diversified through acquisitions. It entered scientific, marine, environmental, and geophysical instrumentation, automotive testing, paper-making machinery, fans and blowers, frequency-control components, and semiconductor technologies. Its Reticon division was associated with BBD and CCD devices. EG&G Biomolecular produced the Acugen 402 automated DNA sequencer, an early commercial system using slab-gel electrophoresis and radioactive Sanger sequencing. The diversification was subsequently reversed. Many non-government divisions were sold in the late 1980s and early 1990s. In 1999, the remaining non-government operations acquired PerkinElmer’s Analytical Instruments Division and adopted the PerkinElmer name. EG&G was wholly owned by The Carlyle Group between 1999 and 2001. In 2002, URS acquired the defense and government-services business, which continued for several years as URS EG&G. URS retired the EG&G name in 2010 as part of a strategy to use one corporate identity. The division became URS Federal Services. After URS was acquired by AECOM in 2014, the relevant government-services activities remained within successor organizations. AECOM sold its Management Services division in 2020 to American Securities and Lindsay Goldberg, creating Amentum. EG&G therefore survives primarily as a historical name associated with U.S. nuclear-test support, defense technology, classified aerospace assistance, and federal technical services. The company also operated the Janet airline service connected with a restricted-use terminal at Las Vegas airport, transporting personnel to remote government locations in Nevada and California. In 2000, EG&G and Raytheon Technical Services formed JT3 LLC for U.S. Air Force range technical services; the operation later became associated with JT4 LLC.
