Bethlehem Steel was once a symbol of American prowess in industrial manufacturing. One of the country’s largest steel producers, it supplied ships and guns for wartime, created steel beams for the first skyscrapers, and ushered in an age of mass production. Steelmaking at its main plant in Bethlehem, Pennsylvania, continued for nearly 150 years, until 1995.
In the heart of the Lehigh plant, in Bethlehem, Pennsylvania, five blast furnaces smelted iron from ore in the first phase of the steelmaking process.
