Cambria Iron Company, East side of Conemaugh River, Johnstown, Cambria County, PA

Significance: The Cambria Ironworks is a part of a National Historic Landmark district recognized for its association with such renowned figures as John Fritz, Captain Bill Jones, Daniel J. Morrell, and William Kelly. It was one of the nation's leading producers of iron and steel rail through the nineteenth century; John Fritz refined his innovative three-high rolling mill at Cambria's rail mill. The works was also the site of of William Kelly's unsuccessful attempts to develop a pneumatic convertor for making steel from pig iron. A number of bitter strikes, most notably in 1873, 1919, and 1937, are associated with the works.
