Andrew J. Farabaugh, the author of three of the documents, was a member of Lehigh’s Class of 1904 graduating as an engineer of mining. His brother Louis Edward Farabaugh, was also a member of the Class of 1904 graduating as a mechanical engineer. Both Farabaugh brothers worked for Bethlehem Steel Company during their engineering careers. The Farabaugh brothers’s hometown was Altoona, Pa. and both seemed to have been familiar with steel factories in western Pennsylvania. Farabaugh was sent by Bethlehem Steel in 1910 to visit European steel manufacturing facilities to observe the European practice of the use of coke oven gas and pig casting machines. Following his trip to Europe, A.J. supervised the refurbishing of blast furnace G for Bethlehem Steel. A. J. Farabaugh was superintendent of Bethlehem Steel Company’s blast furnace G in 1915. This blast furnace was reputed to be one of the finest in the country. Later in his career he returned to his hometown of Altoona, Pa. to work for the Cambria Steel Works. The 1945 report in this collection contains bound blueprints of many Pennsylvania steel plants as they were in 1905 among them the Cambria Steel Works.
