It was built by the Bethlehem Steel Corporation between 1969 and 1972 as its corporate headquarters.","why_significant":"The nomination argues the building is associated with the decline of Bethlehem Steel, which led to its 2001 bankruptcy and the loss of large numbers of jobs in the Lehigh Valley. It presents the tower as a symbol of the corporate decisions made by the company's executive branch in the 1970s and 1980s. The nomination also places the company within the broader history of Pennsylvania's iron and steel industry.","narrative":"Martin Tower is a 332-foot, 21-story office skyscraper on a cruciform plan, built of steel frame with porcelainized steel plate wall panels and plate glass, on a landscaped lawn in Bethlehem. Bethlehem Steel Corporation completed it in 1972 as its headquarters, with a two-level garage beneath a grassed terrace. The top floor held executive offices, a boardroom, a theater and two commercial-grade kitchens, and the building repeats the company's I-beam logo throughout its interior. The nomination argues that the tower is significant for its association with the decline of the company, which had been among the largest steel makers in the country and the region's leading employer. The company's bankruptcy in 2001 cost over one hundred thousand jobs. The building is presented as a physical record of the management decisions made within it during the 1970s and 1980s.","period_of_significance":"1969-1980","architect_builder":"Haines Lundberg Waehler Architects (architect); George A.
