The town was originally called St. Clair City. Served by the Pennsylvania Railroad, it supported coal mining and coking operations beginning in 1886, operated under the names St. Clair Mine & Coke Works, Bradenville Mine & Coke Works and Duquesne Mine & Coke Works.
Mathias W. Saxman's Bradenville Mine & Coke Works built about 40 company houses and a store in the town around 1914. By 1915, its Bradenville Mine employed 195 persons, produced over 110,000 tons of coal and operated 194 beehive coke ovens. The Bradenville Mine ceased operations in 1951.
Researchers in 1994 found that while the store (see Gallery section) and company houses survived, no mine structures remained.
