Éleuthère Irénée du Pont de Nemours (1771–1834) was a French American chemist and industrialist who founded the gunpowder manufacturer, E.I. du Pont de Nemours and Company. Eleuthère Irénée du Pont, the son of Pierre Samuel du Pont de Nemours (1739-1817), was born in Paris on June 24, 1771. In 1787, he was accepted as a student in the Regis des Poudres, a government agency for the manufacture of gunpowder which was directed by Antoine Lavoisier (1743-1794). In 1800 he emigrated to the United States, where he, his father and brother, Victor Marie du Pont (1767-1827), established the commission house Du Pont de Nemours, Père et Fils & Cie.
After consulting with Thomas Jefferson (1743-1826) he established E.I. du Pont de Nemours & Co. in 1802 on the bank of the Brandywine River, just north of Wilmington, Delaware and dissolved the New York commission house, which was only marginally profitable. In the spring of 1803 he settled his family at Eleutherian Mills and wrote to Jefferson seeking government patronage for his new powder factory.
By the War of 1812 E.I. du Pont de Nemours & Co., which had adopted European technology to the American environment, had become one of the largest powder producers in the United States. E.I. du Pont and his sons were active in Whig Party politics, as they were supporters of high protective tariff. On this and other issues he strongly identified with Henry Clay. In 1822 E.I. du Pont was named Director of the Bank of the United States, a position he held until shortly before his death.
Sophie Madeleine Dalmas (1775-1828) was the daughter of Sophie Marie Madeleine Gentil (1744-circa 1829) and Jean Francois Dalmas (1740-1808). E.I. du Pont and Sophie Dalmas du Pont married in 1791, and the couple had eight children, one of whom died in infancy. After their marriage, she lived at the du Pont family estate, Bois des Fossés, with her father-in-law, while her husband worked in his father's printing shop in Paris. When her father-in-law was arrested and imprisoned in Paris in 1794, Sophie du Pont left her eldest child at Bois des Fossés with family members and went to Paris, where she remained until his release a month later. She and other family members left France in 1799, arrived in the United States in 1800, and established housekeeping in Bergen Point, New Jersey. They relocated north of Wilmington, Delaware, along the Brandywine in 1802 and built their home, Eleutherian Mills, a gunpowder manufactory. She suffered a concussion as a result of an explosion at the mills in 1818, never fully recovering, and died at Eleutherian Mills in 1828.

Sophie Dalmas du Pont's papers consist primarily of correspondence with E.I. du Pont. The correspondence between Sophie Dalmas du Pont and her husband dates from 1792 through 1817. Much of the correspondence was written prior to the family's emigration to the United States in 1799 and contains details of their life in France. The letters include information on child rearing, health and medicinal recipes, and diet. The correspondence documents her domestic responsibilities and supervison of the family's farm and vineyards. The letters, affectionate in tone, express the couple's mutual sadness at being apart and reflect a companionate marriage.
