The Duquesne Steel Company began operations in 1886 as a steel rail manufacturer for railroads. In 1888, investors sold the plant to the Allegheny Bessemer Steel Company, which sold it to Carnegie Steel Corporation in 1890. By 1896 the Duquesne Steel Works, as it would later be called, became a fully integrated facility with the addition of two blast furnaces for the production of pig iron. In previous years, the raw iron material had to be purchased from competitors, shipped to Duquesne and processed into the finished steel product.
In 1901, Andrew Carnegie sold his steel corporation to J. Pierpont Morgan and other prominent investors who then created the United States Steel Corporation (USS). U.S. Steel was comprised of subsidiary companies, and Duquesne Works continued to be managed as a part of the USS subsidiary, Carnegie Steel Company. In 1936, the subsidiary's name was changed to the Carnegie-Illinois Steel Company. Duquesne Steel Works experienced a slow but steady expansion and addition period until 1941. The most significant change at this time was the construction of modern electric furnaces for the production of ferromanganese. With the entrance of the United States into World War II, Duquesne Works became a Defense Plant Corporation site and endured a rapid expansion for the production of war material. The 1940s marked Duquesne's peak employment and production period, with nearly 9,000 workers sweating over thirty-two open hearth furnaces. The next major addition to the facility was the large blooming-slopping mills, one-half mile in length, in 1958.
In 1963 U.S. Steel built a basic oxygen process (BOP) steel making furnace at Duquesne Works. While the BOP furnace was considered "modern" technology by American standards, the Japanese and German steel manufacturers had instituted this steel making process by the early 1950s. The BOP furnace performed profitably for USS throughout the 1970s, but its usefulness waned by the early 1980s. U.S. Steel announced the closure of Duquesne Works in 1984. A coalition of United Steelworkers, community leaders, and politicians calling themselves the Tri-State Conference on Steel attempted to block the closing of the Duquesne Works' Dorothy Six furnace. "Save Dorothy" became the rallying cry of protesters in the Pittsburgh area. The closure went through and the Duquesne Works facilities were demolished in 1988.
