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 (1789-1791), 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. This is a letter from du Pont de Nemours to Félix Faulcon (1758-1843), a former member of the Constituent Assembly, in which he describes his arrest and imprisonment in La Force prison in Paris.
