In 1801, French immigrants Eleuthère Irénée "E.I." du Pont (1771-1834) and his father Pierre Samuel "P.S." du Pont de Nemours (1739-1817) organized the E.I. du Pont de Nemours & Company (alternatively referred to as the DuPont Company) in Paris for the purpose of manufacturing gunpowder in the United States. The next year E.I. du Pont purchased a mill site on the banks of the Brandywine Creek just north of Wilmington, Delaware, and the company would grow to be the preeminent gunpowder company in the United States for the next century. This collection comprises the nineteenth-century records of the E.I. du Pont de Nemours & Co. extending to the date of the second incorporation of E. I. du Pont de Nemours & Co. in 1902. The company's twentieth-century records, with the 1902 reincorporation as the dividing point, are described in a separate finding aid as E.I. du Pont de Nemours & Co. twentieth-century records (Accession 0500.II).

During his lifetime, French botanist Michel Adanson (1727-1806) assembled a large number of notes and documents for a projected but never completed scientific encylcopedia. This collection of Adanson's notes focuses on nitrates, including saltpeter.

Pierre Samuel du Pont de Nemours (1739-1817) was a French political economist, writer, publisher, and public administrator. In 1800, accompanied by his sons, Victor Marie du Pont (1767-1827) and Eleuthère Irénée "E.I." du Pont (1771-1834), he arrived in America. In 1802, E.I. du Pont established E.I. du Pont de Nemours & Company, which began manufacturing gunpowder. This item is a letter written to President Thomas Jefferson about du Pont de Nemours' son, E.I. du Pont, as a gunpowder manufacturer and requesting Jefferson's opinon on the matter of refining saltpetre.
