Leisenring (ovens, reclaiming coal and coke), December 1991

The materials in the collection consist of slides, negatives, contact sheets, and photographic prints. The majority of the collection’s materials are original to Dr. Levy, though a small minority are reproductions of historical photographs, images, maps, and postcards. Dr. Levy collected these materials throughout his career for use in class lectures, journal articles, and for an unpublished manuscript–“Tracks from the Past: The Industrial Landscape of the Pittsburgh Region.”
