In 1800 Pierre-Samuel du Pont de Nemours and two sons left France to settle in the United States. This voyage would alter the course of American history. Pierre had been elevated to nobility because of his position with Louis XVI as an economist, secretary to the Assembly of Notables and his assistance in crafting the 1783 Treaty of Versailles that ended the American Revolution. The journey was motivated by the fact that he had been imprisoned during the French Revolution in 1792 and only escaped the guillotine because of the death of Robespierre. After reimprisonment along with his son Eleuthere, in 1797 he made plans to leave the country.
