The Crucible Steel Company of America was formed from the merger of thirteen crucible-steel companies in 1900. This, known as "the great consolidation of 1900", inspired other steel companies to form U.S. Steel a year later. From 1900 through the 20th century, Crucible developed and patented new steels, and brought new steel-production methods to the United States. C. H. Halcomb, Jr. was Crucible's first president and general manager. Two years later, he left Crucible, building the Halcomb Steel mill next door (where he installed the first electric-arc melting furnace in the U.S.).
