Photograph of the blast furnaces at Bethlehem Steel Works Franklin mills in Johnstown, Pennsylvania. The Franklin Mills were built by the newly re-organized Cambria Steel Company in 1898. The mill was purchased by the Midvale Steel & Ordnance Company in 1916, which in turn sold the mill to Bethlehem Steel Company in 1923. Bethlehem Steel closed the mill in 1992.
