Clinton H. Blackburn (1916-1993) was a mechanical engineer with E.I. du Pont de Nemours & Company. Blackburn's papers are a sample of work-related materials he retained upon retirement.

E. I. du Pont de Nemours & Co. (alternatively referred to as the DuPont Company, or simply DuPont) was reincorporated on February 26, 1902, as successor to the partnership Eleuthère Irénée "E.I." du Pont (1771-1834) and his father Pierre Samuel "P.S." du Pont de Nemours (1739-1817) had organized in 1801 for the purpose of manufacturing gunpowder in the United States. During the twentieth century, the company diversified beyond gunpowder and explosives into the broader chemicals industry. The twentieth-century records (dating up to 1972) of E.I. du Pont de Nemours & Co. document the transformation of the company into a modern, centrally administered industrial giant. The collection, however, is not comprehensive for the period, and any company collections received after 1972 were accessioned and processed separately by Hagley Museum and Library.

John M. Barineau (1950-) worked at the DuPont Company for more than forty-five years, serving in a variety of capacities, including operations, product and process development, quality management, product management, capital project management, process safety management, Six Sigma improvements of supply chains, and purchasing, as well as with customers and suppliers working at or visiting approximately seventy DuPont Company sites and contract operations in sixteen countries. E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont company. This small collection of Barineau's papers provides insight into product development. The materials are public information associated with operations that have been sold or terminated or are outdated. These documents show a "behind-the-scenes" view of what was happening within DuPont. The collection has been arranged into five series: Engineering Polymers/Nylon Resins files, Engineering Polymers/Hytrel Polyester Elastomer files, Engineering Polymers improvement initiatives files, DuPont corporate improvement initiatives files, and General files.

Pierre A. Gentieu (1842-1930) was a photographer and a long-term employee of E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont company. Gentieu's papers include correspondence with du Pont family members and coworkers, an account book of powder packed at the Hagley Yard (1858-1902), a record book with lists of explosions (1882-1909), time work sheets of powdermen during the 1890s, and a list of the principal events in the powder yards from 1882 to 1911.
