Pierre Samuel du Pont de Nemours (1739-1817) was a French political economist, writer, publisher, and public administrator. At the onset of the French Revolution, he served as a member of the Assemblée Nationale Constituante, where he allied himself with the moderate Girondist faction. After the leader of the Jacobin movement, Maximilien Robespierre (1758-1794), took power, du Pont was arrested in July 1794, but he escaped execution. On January 3, 1800, accompanied by his sons, he arrived in America. This small collection consists primairly of letters from du Pont de Nemours to Philippe Nicolas Harmand (1759-1839), director of pensions under the Empire, then first clerk for the Public Debt from 1814 to 1821. Harmand was the tutor of du Pont de Nemour's sons and a loyal family friend. Harmand brought du Pont de Nemours food during his period of concealment. These letters include references to financial and business affairs, as well as personal and family news.
