Charles Martin Hall (December 6, 1863 – December 27, 1914) was an American inventor, businessman, and chemist.
 He is best known for his invention in 1886 of an inexpensive method for producing aluminum, which became the first metal to attain widespread use since the prehistoric discovery of iron.
 He was one of the founders of ALCOA.
 Alfred E. Hunt, together with Charles Hall and a group of five other individuals including his partner at the Pittsburgh Testing Laboratory, George Hubbard Clapp, his chief chemist, W.S. Sample, Howard Lash, head of the Carbon Steel Company, Millard Hunsiker, sales manager for the Carbon Steel Company, and Robert Scott, a mill superintendent for the Carnegie Steel Company, Hunt raised $20,000 to launch the Pittsburgh Reduction Company which was later renamed Aluminum Company of America and shortened to Alcoa.
William Walker Scranton (April 4, 1844 – December 3, 1916) was an American businessman based in Scranton, Pennsylvania.
 He became president and manager of the Lackawanna Iron and Coal Company after his father's death in 1872.
 The company had been founded by his father's cousin George W. Scranton.
 Among his innovations, Scranton adopted the Bessemer process for his operations in 1876, greatly increasing production of steel ties with a new mill.
 Scranton founded the Scranton Steel Company, in 1891 consolidated as Lackawanna Iron and Steel Company.
 The steel company became the second largest in the nation.
 He later also managed the Scranton Gas and Water Company, developing a secure water supply outside the city by creating Lake Scranton.
The Lackawanna Steel Company was an American steel manufacturing company that existed as an independent company from 1840 to 1922, and as a subsidiary of the Bethlehem Steel company from 1922 to 1983.
 Founded by the Scranton family, it was once the second-largest steel company in the world (and the largest company outside the U.S. Steel trust).
 Scranton, Pennsylvania developed around the company's original location.
 When the company moved to a suburb of Buffalo, New York, in 1902, it stimulated the founding of the city of Lackawanna.
The Continental Steel Corporation was United States steel producer from 1927 until 1986.
 The company was created on June 21, 1927 through the merger of the Kokomo Steel and Wire Company (founded in Kokomo, Indiana in 1901) with the Superior Sheet Steel Company of Canton, Ohio, and the Chapman Price Steel Company of Indianapolis.
 Among the original eleven directors was John E. Fredrick, who had been an organizer of the Kokomo Fence Machine Company in 1896 and had served on the board of directors of the Kokomo Steel and Wire Company.
 Fredrick served as first Chairman of the Board of Continental Steel, whose headquarters were established in Kokomo.
 The Kokomo operations of this corporation, however, continued to employ the Kokomo Steel and Wire name until 1944.
 Continental Steel was dissolved in 1986, due to bankruptcy.
British Steel Limited is a long steel products business founded in 2016 from assets acquired from Tata Steel Europe by Greybull Capital.

Frederick J. Griffiths (December 11, 1878 - October 17, 1951) was an early, English-born engineer in the Stark County, Ohio steel industry.
 He is best known for working with Henry Ford to develop a vanadium alloy steel in order to produce lighter-weight, stronger automobiles.
 When the Massillon Rolling Mill Company merged into the Central Steel Company in June 1914, Griffiths resigned as a chemist at Canton’s United Steel Company to become Central's vice president and superintendent.
 He then became the president of the company.
 His daughter, Gertrude, lit the first open hearth furnace at the new Central Steel Company in 1915.
 In 1917, Griffith's was named to the Massillon Steel Casting Company board of directors.
 The company's earliest orders came from the United States military for production of the steel-rated equipment and supplies needed for World War I.
 By 1919, 3 of his 5 brothers were all superintendents at Central Steel.
Benjamin Franklin Fairless (May 3, 1890 — January 1, 1962) was an American steel company executive.

The Sloss Mines are a group of mines in southwestern Jefferson County, Alabama.
 They were established by the Sloss Iron and Steel Company and its successor, the Sloss-Sheffield Iron and Steel Company, on the southern end of Red Mountain.
 The Sloss Iron and Steel Company itself was founded by James Sloss in 1881 as the Sloss Furnace Company.
 The Sloss Mines produced iron ore from 1882 until the 1960s.
 The ore that these mines produced were essential to the production of iron at the Sloss Furnaces, consequently making them an important element in the formation of adjacent Birmingham and Bessemer as cities.
The Appleby Frodingham Railway Preservation Society is based at Scunthorpe in North Lincolnshire.
