History
Farrell was incorporated as a city in 1901 and was named after James A. Farrell, a prominent figure in the American steel industry who later served as president of U.S. Steel Corporation. The city grew rapidly in the late 19th and early 20th centuries as steel mills and related manufacturing operations drew waves of immigrant workers seeking employment in the Shenango Valley. Sharon Steel and other industrial enterprises made the area an important center of Pennsylvania's steel production for much of the twentieth century.
