Pierre Samuel du Pont de Nemours (1739-1817) was a French political economist, writer, publisher, and public administrator. He was an advocate for a national educational system and promoted Franco-American trade relations. In 1800, du Pont emmigrated to the United States with his sons Victor Marie du Pont (1767-1827) and Eleuthère Irénée du Pont (1771-1834). This is one letter from du Pont de Nemours to President James Madison (1751-1836) thanking him for his assistance with obtaining travel passes and letters of introduction for his sons. The letter is written in French and is dated July 5, 1812.
