Among its collections, the Maine Historical Society holds the archives of the Portland Company, an engineering firm and foundry incorporated in 1846. Known for both locomotive and marine work, the Portland Company continued as a formidable force in the field until the early 1970s. In 1904, Robert E. Peary contracted with the Portland Company to design and build a marine boiler for the Peary Arctic Club’s ship, SS Roosevelt. The Maine Historical Society houses the engineering drawings of Marine Boiler #257, Engine #93, and Scotch Boiler “For Peary Arctic Club”.
