Background and detail
Background. Du Pont arrived in the United States in 1800, escaping the French Revolution. Although he initially had no intention of manufacturing gunpowder, he possessed expertise in chemistry and gunpowder making during a period when American-made powder quality was poor. Delaware legend suggests a hunting trip with Major Louis de Tousard influenced his decision to enter the business.
Establishment. With his father's blessing, Du Pont assembled capital for the first powder mills, returning to France in 1801 to procure financing and equipment. The act of association was signed on 21 April 1801, christening the company E.I. du Pont de Nemours & Company. By 1802, he had established both his business and his family home, Eleutherian Mills, on the Brandywine Creek.
Operations. The first gunpowder was produced in April 1804. The company grew quickly, becoming the largest supplier of gunpowder to the U.S. military by the mid-19th century. It supplied as much as 40 percent of the powder used by the Union Army during the American Civil War, establishing its role in Delaware's development.
