Overview
Illinois Steel Company was a major American iron and steel producer that operated during the rapid industrial expansion of the United States in the late nineteenth century. Its corporate origins reached back to the North Chicago Rolling Mill, established in Chicago by Eber Brock Ward in 1857 to reroll iron rails. After the introduction of the Bessemer process, the mill was converted to steel production in 1865, helping establish the industrial base from which Illinois Steel later developed. The Illinois Steel Company itself was created in 1889 through the consolidation of the North Chicago Rolling Mill Company, the Union Iron Company, and the Joliet Steel Company. The constituent businesses gave the new company a network of works in Chicago, South Chicago, Milwaukee, and Joliet. The company was headquartered in Chicago's Rookery Building and maintained branch offices in several major American cities, including New York, Saint Paul, Cleveland, St. Louis, and Denver. This office network reflected an effort to sell steel across the expanding national railroad and construction markets rather than limiting the business to the Great Lakes region. Illinois Steel became the largest steel company in Illinois and one of the largest iron and steel producers in the United States. Its industrial assets extended beyond mills. The company held a controlling interest in the Chicago, Lake Shore and Eastern Railway and owned or controlled access to coal mines in West Virginia and Pennsylvania, iron mines in Michigan and Wisconsin, and limestone mines in Indiana. These holdings supported vertical integration by linking raw-material supply, transportation, and steelmaking. By the late 1880s, the company was reported to produce more than 1.1 million tons of pig iron and approximately one million tons of steel. Its principal products included railroad rail, rail fastenings, steel plates, pig iron, wire, mineral wool, and hydraulic Portland cement. Railroad customers identified in historical accounts included the Atchison, Topeka & Santa Fe; Wabash; Chicago & Alton; and Baltimore & Ohio. The company also participated in bridge-related manufacturing, and steelwork associated with Illinois Steel has been attributed to a number of historic bridges in the American Midwest and Southwest. Pig-iron operations were conducted in conjunction with Pickands, Brown & Company. The company's growth was challenged by Carnegie Steel, whose Pittsburgh operations were considered more efficient and which had stronger access to some markets. Carnegie attempted to pressure Illinois Steel by selling steel near Chicago at prices reported to be below Illinois Steel's production costs. By 1896, Illinois Steel had prepared papers for a receivership. Rather than proceed immediately, management shifted its attention toward markets west of Chicago, where Carnegie's supply lines were weaker. The strategy allowed Illinois Steel to avoid the contemplated receivership and preserve its position. In 1898, Illinois Steel absorbed the Minnesota Iron Company, the Lorain Steel Company of Ohio, the Johnson Company of Pennsylvania, and the Elgin, Joliet & Eastern Railway. The enlarged combination became the Federal Steel Company. Elbert Henry Gary, who had served as Illinois Steel's general counsel, became president of Federal Steel. Gary subsequently worked with financier J. P. Morgan in the acquisition of Carnegie Steel. Federal Steel was then combined with Carnegie Steel and other interests to create United States Steel Corporation, which began operations on April 1, 1901. Illinois Steel therefore ceased to exist as an independent company, but its mills, resources, transportation interests, and product capabilities became part of the industrial foundation of U.S. Steel.
History
Illinois Steel Company's history developed from the transformation of Chicago's early iron-rolling industry into modern steelmaking. In 1857, Eber Brock Ward established the North Chicago Rolling Mill to reroll iron rails. The business was among the industrial enterprises that supplied the expanding railroad system of the United States. Following the arrival of the Bessemer process, the mill was converted to steel production in 1865. Other predecessor operations were also established during the nineteenth century, including the Union Iron Company in Chicago in 1863, the Joliet Steel Company in 1870, and a Milwaukee plant associated with the North Chicago Rolling Mill Company in 1868. In 1889, these enterprises were consolidated into Illinois Steel Company. The combination brought together plants in Chicago, South Chicago, and Milwaukee, as well as the Joliet operation. The company based its main office in the Rookery Building in downtown Chicago and operated sales or branch offices in New York, Saint Paul, Cleveland, St. Louis, and Denver. Its geographic organization corresponded to the nationwide demand for rails, steel plates, and other industrial products generated by railroad construction and urban development. Illinois Steel pursued scale and control over key inputs. It held a controlling interest in the Chicago, Lake Shore and Eastern Railway and owned or controlled mines supplying coal, iron ore, and limestone. Coal properties were located in West Virginia and Pennsylvania, iron resources in Michigan and Wisconsin, and limestone resources in Indiana. This combination of manufacturing, transportation, and raw-material interests helped Illinois Steel compete as an integrated producer. Historical accounts describe output in the late 1880s of more than 1.1 million tons of pig iron and about one million tons of steel, making the company one of the largest producers in the country. The company's product range centered on railroad and industrial materials. It produced rail, rail fastenings, steel plates, pig iron, wire, mineral wool, and hydraulic Portland cement. Its rail products were used by several important railroads, including the Atchison, Topeka & Santa Fe, Wabash, Chicago & Alton, and Baltimore & Ohio. Illinois Steel's manufacturing legacy also appears in records concerning historic bridges, with works attributed to the company in Iowa, Nebraska, Arizona, Texas, and other locations. Some bridge attributions involve successor or related bridge companies, so individual construction responsibilities vary by structure. Growth brought substantial competitive risk. Carnegie Steel, operating from Pittsburgh, was regarded as having a more efficient production system. It attempted to weaken Illinois Steel in the Chicago market by offering steel at prices reported to be as low as eighteen cents per ton, compelling Illinois Steel to sell below its production cost. In 1896, Illinois Steel had prepared documentation for a receivership. Before filing, however, it adopted a market strategy centered on areas west of Chicago, where Carnegie's logistical reach was less effective. This decision enabled Illinois Steel to continue operating independently for a further period. The next stage was corporate combination. In 1898, Illinois Steel acquired or combined with the Minnesota Iron Company, Lorain Steel Company of Ohio, Johnson Company of Pennsylvania, and the Elgin, Joliet & Eastern Railway. The enlarged enterprise was organized as Federal Steel Company. Elbert Henry Gary, who had been Illinois Steel's general counsel, became Federal Steel's president. Gary then worked with J. P. Morgan to arrange the acquisition of Carnegie Steel. Once that transaction was approved, Federal Steel was combined with Carnegie Steel and other businesses to create United States Steel Corporation. U.S. Steel commenced operations on April 1, 1901, ending Illinois Steel's existence as an independent corporate entity and transferring its industrial assets into one of the largest steel companies of the era.
