Du Pont Family Legacy

Nemours Mansion and GardensThe story of Delaware and the Brandywine Valley is inextricably intertwined with the story of the du Pont family. It's a story that begins when Pierre Samuel du Pont de Nemours, the son of a Paris watchmaker, left his native country for the United States with his two sons in 1800.  Two years later, his son Éleuthère Irénée du Pont opened a gunpowder mill on the banks of the Brandywine Creek, near Wilmington

A great company was born. And with it, a great relationship between a family and the people of Delaware.

Over time, the Du Pont Company diversified and expanded to become one of the leading chemical and health care companies in the world. The du Ponts built great estates throughout the Brandywine Valley, and their familial commitment to conservation and natural beauty ensured the preservation of much of the region.

The original gunpowder mill became HAGLEY MUSEUM AND LIBRARY. Pierre Samuel du Pont, great-great grandson to the original Pierre, planted some of the first gardens on the estate that is now LONGWOOD GARDENS. Alfred Irénée du Pont, another great-great grandson, built NEMOURS MANSION as a gift for his second wife, Alicia. Henry Francis du Pont built the 175-room WINTERTHUR estate in Greenville for his family, before opening it to the public.

Museums. Gardens. Performing arts centers. Even highways, hotels, and open spaces. In every corner of Delaware, there's a piece of the du Pont family legacy to be admired and remembered.
