The Antietam Woolen Manufacturing Company was a small textile mill in Funkstown, Maryland, and operated a domestic store in Hagerstown. The collection contains an incomplete record of a small textile mill company in the early nineteenth century. The records include bills, orders, accounts, inventories, and cost estimates. Of particular interest are a series of reports on visits to similar mills operated by Du Pont, Bauduy & Company near Wilmington, Delaware, and by Fisher & Gougher in Germantown, Pennsylvania, with notes on workers, machinery, and administrative methods.

Charles I. du Pont & Company was a woolen factory. The firm was initially established as Du Pont, Bauduy & Co., but after its dissolution in 1815, it became the partnership of Victor & Charles I. du Pont de Nemours & Co. In 1827, the firm transitioned into Charles I. du Pont and Company and operated as such until 1856. This small collection includes twelve letter invoices for sky-blue cloth, dated 1840 and 1856.

Several early companies, established by members of the du Pont family, operated on the Brandywine Creek in proximity to the mills of E.I. du Pont de Nemours & Co. These businesses included factories that produced tanned leather, woolen and cotton cloth, and yarns. The firms also owned properties that were used by, or sold to, other developers of mills in the region. This collection includes the papers of Du Pont, Bauduy & Company (1803-1815); Du Planty, McCall & Company (1813-1837); Brandywine Mill Seat Company (1798-1854); A. Cardon & Company (1824-1833); and Rockland Manufacturing Company (1825-1856).

Geist & Geist, Inc., was a manufacturer of women's knitwear products, typical of the small, flexible family firms that dominated New York City's famous Garment District for much of the twentieth century. The records of Geist & Geist, Inc., document the activities, especially design, publicity and marketing.

Victor Marie du Pont (1767-1827) was a French diplomat who later immigrated to the United States and established various trading companies before moving to Delaware. He was the eldest son of Pierre Samuel du Pont de Nemours (1739-1817). The collection consists of correspondence, business and personal papers, and writings of Victor Marie du Pont and his wife, Gabrielle Joséphine (de la Fite de Pelleport) du Pont.
