Pierre Samuel du Pont de Nemours (1739-1817) was a noted French Physiocrat and economic advisor to Jacques Necker (1732-1804) and King Louis XVI (1754-1793). In 1784, Louis XVI made him a noble through the process of noblesse de lettres, which added the de Nemours suffix to his name. In the early 1780s he was involved in the negotiations which led to the Anglo-French Commercial Treaty of 1786. In 1786 he was appointed Counseiller d'Etat by Louis XVI, and the next year he served as secretary of the first Assemblée des Notables convened at Versailles. He also served as a member of the Assemblée Nationale Constituante (1789-1791), where he allied himself with the moderate Girondist faction. In the aftermath of the French Revolution he and his family emigrated to the United States where his son Eleuthère Irénée du Pont (1771-1834) established the gun powder manufacturer E.I. du Pont de Nemours & Company.
