The United States Radium Corporation was a company, most notorious for its operations between the years 1917 to 1926 in Orange, New Jersey, in the United States that led to stronger worker protection laws.
 After initial success in developing a glow-in-the-dark radioactive paint, the company was subject to several lawsuits in the late 1920s in the wake of severe illnesses and deaths of workers (the Radium Girls) who had ingested radioactive material.
 The workers had been told that the paint was harmless.
 During World War I and World War II, the company produced luminous watches and gauges for the United States Army for use by soldiers.
The Plymouth Cordage Company was a rope making company located in Plymouth, Massachusetts, USA.
 The company, founded in 1824, had a large factory located on the Plymouth waterfront.
 By the late 19th century, the Plymouth Cordage Company had become the largest manufacturer of rope and twine in the world.
 The company specialized in ship rigging, and was chosen among other competitors in the early 1900s to manufacture the rope used on the USS Constitution.
 The company's twine, Plymouth binder twine, popular among farmers, was the inspiration for the naming of the "Plymouth" brand of automobiles first produced in 1928.
Undark was a trade name for luminous paint made with a mixture of radioactive radium and zinc sulfide, as produced by the U.S. Radium Corporation between 1917 and 1938.
 It was used primarily in watch and clock dials.
 The people working in the industry who applied the radioactive paint became known as the Radium Girls, because many of them became ill and some died from exposure to the radiation emitted by the radium contained within the product.
 The product was the direct cause of Radium jaw in the dial painters.
 Undark was also available as a kit for general consumer use and marketed as glow-in-the-dark paint.
Radium dials were almost always painted by young women, who used to 'point' their brushes by licking and shaping the bristles prior to painting the fine lines and numbers on the dials.
 This practice resulted in the ingestion of radium, which caused serious jaw-bone degeneration and malignancy and other dental diseases reminiscent of phossy jaw.
 The disease, radium-induced osteonecrosis, was recognized as an occupational disease in 1925 after a group of radium painters, known as the Radium Girls, from the United States Radium Corporation sued.
 By 1930, all dial painters stopped pointing their brushes by mouth.
 Stopping this practice drastically reduced the amount of radium ingested and therefore, the incidence of malignancy, to zero by 1950 among the workers who were studied.
The V. G. Khlopin Radium Institute, also known as the First Radium Institute, is a research and production institution located in Saint Petersburg specializing in the fields of nuclear physics, radio- and geochemistry, and on ecological topics, associated with the problems of nuclear power engineering, radioecology, and isotope production.
 It is a subsidiary company of the Rosatom Russian state corporation.
The Philadelphia Lyric Opera Company was an American opera company located in Philadelphia, Pennsylvania that was active between 1958 and 1974.
 The company was led by a number of Artistic Directors during its history, beginning with Aurelio Fabiani.
 Other notable Artistic Directors include Julius Rudel and Anton Guadagno (1966–1972).
 The company produced between four and six of their own operas every year in addition to sponsoring numerous traveling productions from the New York City Opera.
 In 1975 the company merged with the Philadelphia Grand Opera Company but retained its original name.
 With the combined resources of both companies, the Philadelphia Lyric Opera Company began producing higher quality productions with name artists such as Luciano Pavarotti, Joan Sutherland, Roberta Peters, Montserrat Caballé, and others.
 For the bicentennial year 1976, the company commissioned famed opera composer Gian Carlo Menotti to create a new opera.
 The work, The Hero, premiered on June 1, 1976.
 In 1980, the company artistically reorganized to form the Opera Company of Philadelphia.
The Boulton Carbon Company was a manufacturing company located in Cleveland, Ohio, USA, from 1881 to 1886.
 It was devoted to the manufacture of carbon points (or carbons) used for arc lighting.
 The company was organized in 1881 by W. H. Boulton and Willis U. Masters and formally incorporated in 1883.
 A controlling interest in the company was acquired in 1886 by a group of investors led by Washington H. Lawrence.
 In 1886, Lawrence reorganized the Boulton Carbon Company as the National Carbon Company.
 Under the leadership of Lawrence, the National Carbon Company became the dominate carbon company in the United States and was one of the founding members of the Union Carbide & Carbon Company in 1917.
The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint.
 Painting was done by women at three different sites in the United States, and the term now applies to the women working at the facilities.
 The first, United States Radium factory in Orange, New Jersey, beginning around 1917, at Ottawa, Illinois, beginning in the early 1920s, and a third facility in Waterbury, Connecticut.
The Oregon Iron Company was an iron smelting company located in what is now Lake Oswego, Oregon.
 The company was established in 1865, and in 1867 became the first company west of the Rocky Mountains in the United States to smelt iron.
 The company failed after a few years, but was reorganized as the Oswego Iron Company in 1878, and again as the Oregon Iron and Steel Company in 1883.
 With the addition of a larger furnace, the last incarnation of the company prospered, reaching peak production in 1890.
 By 1894, however, pressure from cheaper imported iron combined with the effects of the Panic of 1893 forced the company to close its smelter.
 The company continued to operate a pipe foundry until 1928, and until the early 1960s, existed as a land management company, selling its real estate holdings which expanded the city of Lake Oswego.
