Calmar Steamship Company
Calmar Steamship Company was a proprietary subsidiary of the Bethlehem Steel founded in New York City in 1927. Bethlehem Steel Company founded Calmar Steamship Company and other steamship companies after finding general shipping companies could not meet the company's needs in a timely manner. At the time Bethlehem Steel Company was the second-largest steelmaker in the United States and the world, only behind U.S. Steel. Calmar Steamship Company shipped Bethlehem Steel Company products from the Atlantic coast to the Pacific coast. On the return trip, Calmar Steamship Company would bring lumber products from the Pacific coast to the Atlantic coast. Calmar Steamship Company closed in 1976, as United States steel manufacture declined in the 1960s. Ships
