General Electric Company

General Electric Company (GE) is an American multinational conglomerate incorporated in New York and headquartered in Boston. As of 2018, the company operates through the following segments: aviation, healthcare, power, renewable energy, digital industry, additive manufacturing, venture capital and finance, lighting, and oil and gas.
Led by Sanford Alexander Moss, GE moved into the new field of aircraft turbo superchargers. GE introduced the first set of superchargers during World War I, and continued to develop them during the interwar period. Superchargers became indispensable in the years immediately prior to World War II. GE supplied 300,000 turbo superchargers for use in fighter and bomber engines. This work led the U.S. Army Air Corps to select GE to develop the nation's first jet engine during the war. This experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine that was demonstrated in the United States in 1941. GE was ranked ninth among United States corporations in the value of wartime production contracts. Although, their early work with Whittle's designs was later handed to Allison Engine Company. GE Aviation then emerged as one of the world's largest engine manufacturers, bypassing the British company, Rolls-Royce plc.
In 1962, GE started developing its GECOS (later renamed GCOS) operating system, originally for batch processing, but later extended to timesharing and transaction processing. Versions of GCOS are still in use today. From 1964 to 1969, GE and Bell Laboratories (which soon dropped out) joined with MIT to develop the Multics operating system on the GE 645 mainframe computer. The project took longer than expected and was not a major commercial success, but it demonstrated concepts such as single level store, dynamic linking, hierarchical file system, and ring-oriented security. Active development of Multics continued until 1985.
GE heavily contaminated the Hudson River with polychlorinated biphenyls (PCBs) between 1947 and 1977. This pollution caused a range of harmful effects to wildlife and people who eat fish from the river or drink the water. In response to the contamination, activists protested in various ways. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. In 1983, the United States Environmental Protection Agency (EPA) declared a 200-mile (320 km) stretch of the river, from Hudson Falls to New York City, to be a Superfund site requiring cleanup. This Superfund site is considered to be one of the largest in the nation. Other sources of pollution, including mercury contamination and sewage dumping, have also contributed to problems in the Hudson River watershed.
GE Healthcare is collaborating with The Wayne State University School of Medicine and the Medical University of South Carolina to offer an integrated radiology curriculum during their respective MD Programs led by investigators of the Advanced Diagnostic Ultrasound in micro-gravity study. GE has donated over one million dollars of Logiq E Ultrasound equipment to these two institutions.
