The International Navigation Company (INC) was a Philadelphia based holding company owning 26 ships totaling 181,000 tons and carried more passengers than either Cunard or White Star, when the company was reorganized as International Mercantile Marine in 1902. INC was formed in 1871 with the backing of the Pennsylvania Railroad to operate foreign flagged vessels on transatlantic routes to Philadelphia. Clement Griscom, the company’s general manager, entered into an agreement with the Belgian Government to establish the Red Star Line to operate a mail service out of Antwerp to Philadelphia and New York.
