E. I. du Pont de Nemours and Company, commonly referred to as DuPont, is an American conglomerate that was founded in July 1802 as a gunpowder mill by Éleuthère Irénée du Pont.
DuPont was founded in 1802 by Éleuthère Irénée du Pont, using capital raised in France and gunpowder machinery imported from France. The company was started at the Eleutherian Mills, on the Brandywine Creek, near Wilmington, Delaware, two years after he and his family left France to escape the French Revolution. It began as a manufacturer of gunpowder, as du Pont noticed that the industry in North America was lagging behind Europe. The company grew quickly, and by the mid-19th century had become the largest supplier of gunpowder to the United States military, supplying half the powder used by the Union Army during the American Civil War. The Eleutherian Mills site is now a museum and a National Historic Landmark.
