Overview

Cooper Industries was an American multinational industrial manufacturer whose history stretched from a nineteenth-century Ohio foundry to a diversified producer of electrical equipment, power systems, lighting, safety products, tools, and industrial technologies. Founded in 1833 by brothers Charles and Elias Cooper in Mount Vernon, Ohio, the business initially made agricultural and domestic metal goods, including plows, livestock troughs, kettles, and stoves. It later concentrated on steam engines and then moved into gas-engine technology as steam power became less central to industrial development. The company's gas-engine expertise became especially important as oil and gas infrastructure expanded. Following its combination with Bessemer Gas Engine Company, the Cooper-Bessemer business became a significant supplier of pipeline-compression engines and related equipment. During the Second World War, Cooper-Bessemer supplied engine components used in naval minesweepers and Liberty Ships, linking the company to the industrial mobilization of the United States and its allies. After the war, Cooper pursued diversification. Over the following decades it expanded beyond engines and energy equipment into electrical products, power-delivery systems, automotive components, tools, hardware, lighting, and safety equipment. Acquisitions were a major part of this strategy. The purchases of Crouse-Hinds in 1981 and McGraw-Edison in 1985 strengthened its electrical, lighting, and industrial portfolio, while later transactions added businesses such as MTL Instruments Group and Wheelock. By the 1990s, Cooper was rationalizing its portfolio and reducing exposure to cyclical automotive and petroleum activities. The company increasingly centered its operations on two broad areas: an Electrical Products Group and an Energy and Safety Solutions group. Its portfolio included well-known businesses and brands such as Bussmann fuses, Crouse-Hinds hazardous-location equipment, Cooper Lighting, Cooper Power Systems, Cooper Wiring Devices, and Cooper Safety. In 2011, industrial and utility customers accounted for most of its sales, and approximately 40 percent of revenue came from outside the United States. The company operated manufacturing facilities in 23 countries at that time. Cooper reincorporated in Bermuda in 2002. In 2010, its hand-tools operations joined Danaher Tool Group to form Apex Tool Group, a joint venture that was subsequently sold to Bain Capital in 2012. The same year, Eaton announced and completed its acquisition of Cooper Industries. Cooper was consequently removed from the S&P 500 index and its businesses were integrated into Eaton's electrical and industrial operations. Former Cooper divisions continued under Eaton names or as Eaton business units, including Eaton's Bussmann, Crouse-Hinds, Cooper Lighting Solutions, Cooper Power Systems, Cooper Safety, Cooper Wiring Devices, and B-Line businesses. Eaton later sold its lighting business to Signify in 2020, affecting the former Cooper Lighting portfolio.

History

Cooper Industries began in 1833 when Charles and Elias Cooper established a foundry in Mount Vernon, Ohio. Its earliest products were practical cast-metal goods for farms and households, including plows, hog troughs, kettles, and stoves. During the nineteenth century the company moved toward steam engines, responding to the growing importance of mechanized power in American industry. When steam power became less dominant late in the century, Cooper shifted again, developing gas engines. Its expertise became closely connected with the expansion of oil and gas infrastructure, particularly pipeline compression. A merger with Bessemer Gas Engine Company created Cooper-Bessemer and helped establish the business as a major American producer of pipeline-compressor engines. Cooper-Bessemer contributed to wartime manufacturing during the 1940s. Its engine components were used in much of the U.S. Navy's minesweeper fleet and in Liberty Ships, which transported a large share of Allied wartime cargo. Following the war, the company sought broader and less concentrated sources of revenue. It entered electrical equipment, power systems, automotive products, tools, hardware, and lighting through internal development and acquisitions. Two important acquisitions were Crouse-Hinds in 1981 and McGraw-Edison in 1985. These transactions expanded Cooper's presence in hazardous-location electrical equipment, lighting, power products, and related industrial markets. During the 1990s, Cooper reviewed its portfolio and reduced its exposure to more cyclical automotive and petroleum activities. The resulting company was increasingly organized around electrical products and energy-and-safety solutions. Cooper's later portfolio included Bussmann fuses; Crouse-Hinds and CEAG equipment for hazardous and explosive environments; Halo, Metalux, and other lighting brands; Cooper Power Systems equipment for utility networks; Cooper Wiring Devices; Cooper Safety; and B-Line support and enclosure systems. The company also retained tool businesses for a time. In 2002, Cooper reincorporated in Bermuda. In 2008 it announced the acquisition of MTL Instruments Group, extending its instrumentation and hazardous-area capabilities. In 2010, Cooper's hand-tools operation was combined with Danaher Tool Group in the Apex Tool Group joint venture. Apex was sold to Bain Capital in 2012. Separately, Eaton agreed to acquire Cooper Industries, completing the transaction on November 30, 2012. Cooper ceased to exist as an independent public company, its former businesses becoming Eaton divisions or business units. In 2020, Eaton sold its lighting business to Signify, transferring the former Cooper Lighting activities into Signify's ownership.
