ThePennsylvania Steel Company was the name of two Pennsylvania steel companies.
The original company was established in late 1865 by:J. Edgar Thomson, president of thePennsylvania Railroad,Samuel Morse Felton Sr., recently retired president of thePhiladelphia, Wilmington and Baltimore Railroad, andNathaniel Thayer III of theBaldwin Locomotive Works. Felton, named president in January 1866, chose the 100-acre site of modern-daySteelton, Pennsylvania to build the first steel mill, purchasing land from Henry A. and Rudolph F. Kelker after obtaining theBessemer license fromBurden Iron Works inTroy, New York.[1]Alexander Lyman Holley, the steel pioneer who first brought this process to America, was chosen to build the mill, and mansion for Felton, which was completed in 1867 along the banks of theSusquehanna River and next to thePennsylvania Canal, and became operational on May 15, 1868.[2] It consisted ofblast furnaces and aBessemer process mill. The company was acquired byBethlehem Steel in 1917 and, by 1960, the open hearth furnaces were closed by a single blast furnace.Open hearth furnaces continued to operate until 1968 when they were replaced byelectric arc furnaces. In 1983, acontinuous caster was installed at the plant. Bethlehem Steel declaredbankruptcy in 2001 and the plant was acquired byInternational Steel Group, which later merged intoMittal and thenArcelorMittal.[3]
The second Pennsylvania Steel Company was originally known as thePennsylvania Steel & Aluminum Company, and was established in 1972 inHuntingdon Valley, Pennsylvania. It produces machines and manufactures steel and aluminum products but is not involved in basic steel production. The company was renamed the Pennsylvania Steel Company in 1988 and moved its production from Huntington Valley toBensalem Township, Pennsylvania, in 1993.[4]
