Bethlehem Key Highway Shipyard started as William Skinner & Sons in downtown Baltimore, Maryland in 1815. In 1899 the shipyard was renamed Skinner Shipbuilding & Dry Dock Company. Also at the site was Malster & Reanie started in 1870 by William T. Malster (1843–1907). In 1879 Malster partnered with William B. Reaney (1808-1883). In 1880 Malster & Reanie was sold and renamed Columbian Iron Works & Dry Dock Company (Lower Yard). Malster & Reanie and Skinner Shipbuilding & Dry Dock Company merged in 1906, but remained as Skinner Shipbuilding. In 1914 the company was renamed Baltimore Dry Dock & Shipbuilding Company. Baltimore Dry Dock & Shipbuilding Company sold to Bethlehem Steel in 1922, becoming part of Bethlehem Shipbuilding Corporation. Bethlehem Steel operated the shipyard for ship repair, conversion and some ship construction. Bethlehem's main ship construction site was across the harbor at Bethlehem Sparrows Point. Bethlehem Key Highway Shipyard was known as the Bethlehem Upper Yard located north-east side of Federal Hill. Bethlehem Fort McHenry Shipyard located on the west side of Locust Point peninsula was known as the Lower Yard, near Fort McHenry.[1]
