About Cramp and Sons

William Cramp & Sons Shipbuilding Company of Philadelphia was founded in 1825 by William Cramp. When the yard opened in 1830, Cramp was one of at least thirteen private shipbuilding establishments operating along the Philadelphia waterfront. Seventy years later, it was the only one of the original group which was still operating. Cramp was one of the few American shipbuilders to survive the transition from a craft mode of production focused around wooden sailing vessels to an industry centered around steam engines and iron and steel construction; from canvas and rope to mechanical devices including refrigeration, lighting, and telegraph equipment. The American Ship & Commerce Corporation bought the yard in 1919 but closed it in 1927 as fewer ships were ordered by the U.S. Navy after passage of the Naval Limitations Treaty in 1923. In 1940, the Navy spent $22 million to reopen the yard to build cruisers and submarines. Cramp closed in 1947 and the site, on the Delaware River, became an industrial park.
