The creation of the United States parallels the development of the American iron industry, exemplified by the fact that seven signers of the Declaration of Independence were ironmasters.  Although Britain attempted to stem the colonies’ iron production, by the Revolution, the colonies were one of the world’s largest iron producers.  The iron sites supplied products for the war for independence, and the ironmasters were actively involved in politics.  The iron industry was central in the fight for American independence.

Mary Ann Furnace was built in 1762 by George Stevenson, George Ross, and William Thompson. This furnace is believed to be the first charcoal furnace built on the western side of the Susquehanna River. The furnace manufactured pans, kettles, utensils, and five-plate stoves. It also supplied cannon balls and grapeshot for the continental army. No structures remain of the ironworks.
