Longwood Manuscripts

About this collection

The Longwood Manuscripts comprise the manuscript collections of P. S. du Pont (1870-1954). They made up the core collection of the former Longwood Library, and later the collection became known as The Longwood Manuscripts after the library merged with the Hagley Museum in 1961. The collection is an invaluable resource, tracing the history of the du Pont family from eighteenth-century France to 1954. This online collection is a small selection of materials from the Longwood Manuscripts. Many of the items digitized to date relate to the early history of the E.I. du Pont de Nemours & Company and include correspondence, other business papers, and drawings of powder mills and machinery by Eleuthère Irénée du Pont. Additional items relate to other early du Pont business ventures in the United States, including Du Pont, Bauduy & Company; Du Planty, McCall & Company; and Brandywine Mill Seat Company.
