After several clashes with Morgan and fellow US Steel executive Elbert Gary, Schwab left USS in 1903 to run the Bethlehem Shipbuilding and Steel Company in Bethlehem, Pennsylvania. The company had gained shipyards in California, Delaware, and New Jersey through its brief but fortunate involvement as one of the few solvent enterprises in United States Shipbuilding Company. Under his leadership (and that of Eugene Grace), it became the largest independent steel producer in the world. A major part of Bethlehem Steel's success was the development of the H-beam, a precursor of today's ubiquitous I-beam. Schwab was interested in mass-producing the wide flange steel beam, but that was a risky venture that required raising capital and building a large new plant, all to make a product whose ability to sell was unproven. In his most famous remark, Schwab told his secretary, "I've thought the whole thing over, and if we are going bust, we will go bust big."
