The duPont Family Legacy
Alfred I. du Pont created Nemours in 1909-10 as a gift for his second wife, Alicia. The name honors the north-central French town affiliated with his great-grandfather.
The mansion was designed by the New York firm Carrère and Hastings in the 18th-century neoclassical style. Alfred personally supervised construction details, insisting on period-authentic techniques and materials.
The duPont fortune came from explosives manufacturing that dominated American industry for over a century. Alfred’s holdings in E.I. du Pont de Nemours and Company funded The Nemours Foundation.
Connection to Children’s Healthcare
The Nemours Foundation was incorporated in Florida in 1936. In 1940, the original Alfred I. duPont Institute opened in Wilmington as a pediatric orthopedic institute. This modest hospital has grown into one of the nation’s largest pediatric health systems.
As of December 2023, the duPont Charitable Trust’s portfolio is worth almost $10 billion, helping financially support Nemours Children’s Health. This endowment ensures Alfred duPont’s vision of improving children’s health continues nearly 90 years after his death.
