Charles Lee Reese Sr. (1862-1940) was a chemist and scientist at the E. I. du Pont de Nemours & Company from 1902 to 1931. Until 1900 he taught chemistry in several American schools, and then began his career in industrial research with the New Jersey Zinc Company. The collection consists of nineteen volumes of Reese's laboratory notebooks, most dating from his tenure at New Jersey Zinc. A minority of the notebooks cover some of his early work for DuPont.

Charles Milton Cooper (1900-1971) was a chemical engineer and an executive at the E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont company. His papers primarily include notes and photographs produced during his time conducting bubble formation experiments at the DuPont Company’s Belle Plant, in Charleston, West Virginia.

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 The materials are public information associated with operations that have been sold or terminated or are outdated.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.

Peter K. Baumgarten (1926-2000) was a chemical engineer for the DuPont Company for thirty years who continued as a consultant for the company after his retirement. He worked as a chemical engineer for DuPont and Westinghouse, retiring from the Savannah River Site in 1993. He also taught math and physics part-time at the University of South Carolina (USC)-Aiken. This small collection consists of papers, speeches, notes, presentations, and articles that Baumgarten wrote while working at DuPont as a chemical engineer and then as a consultant. His research focused on ion exchange for decontamination and waste removal from radioactive sources such as the Savanah River Plant.

Engineer's notebook kept by future DuPont Company vice president Willis F. Harrington (1882-1960) while an entry-level engineer at the Barksdale Works in Wisconsin.
