In 1917, the Carnegie Steel Company was a subsidiary of the United States Steel Corporation. The Carnegie Steel Company produced Bessemer and open hearth steel in various grades.
Carnegie Steel Company was an American steel company based in Pittsburgh, Pennsylvania, and founded by Scottish-born American industrialist Andrew Carnegie and a handful of associates in the late 1800s. The name Carnegie Steel Company can refer to Carnegie’s first steel plant, which opened in 1875, as well as to the vast network of steel mills he built and purchased in the late 1880s and early 1890s.
By the time the corporation was sold in 1901, Carnegie had amassed a veritable empire of steel production along the Allegheny, Monongahela, and Ohio rivers. Each production site was supplied by Carnegie-owned mines and coke fields, and their goods were transported by Carnegie river barges. The consolidation of these steel mills and their eventual sale made Carnegie one of the richest persons in the United States at the time.
