Charles J. Pedersen papers
Charles J. Pedersen (1904-1989) spent more than forty years as a DuPont research chemist in the Organic Chemicals and Elastomer Chemicals departments. Pedersen’s early investigations led to the development of a dramatically improved process for manufacturing tetraethyl lead, an important gasoline additive. His discoveries relating to the degradative effects of heavy metals on petroleum products resulted in thirty patents for antioxidants and other related products. Pedersen’s greatest achievement, however, came toward the end of his career when he discovered a new class of molecules that he called "crown compounds." Twenty years after his ground-breaking discovery was first disclosed publicly, Pedersen shared the Nobel Prize in Chemistry. Pedersen’s research notebooks provide detailed accounts of laboratory preparations and analytical procedures. Also included in this collection are files compiled by Pedersen relating to his original research on crown compounds, as well as his earlier research.
Charles L. Reese laboratory notebooks
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.
E.I. du Pont de Nemours & Company, Organic Chemicals Department, Dyestuffs Division manuals and notebooks

By the late 1920s the DuPont Company was one of the four major U.S. dye producers and controlled twenty-five percent of the market. The records consist of notebooks and procedures on dyes, which describe the colors, uses, applications, tests, and fastness and dying properties for dyes manufactured by DuPont and its competitors.
Francis Gurney du Pont papers
Francis Gurney du Pont (1850-1904) was the youngest son of Alexis I. du Pont (1816-1857) and Joanna Smith du Pont (1815-1876), and grandson of Éleuthère Irénée "E.I." du Pont (1771-1834), founder of E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont Company. The papers consist of du Pont's student lecture and laboratory notes; letters; technical notes and papers; records of gunpowder production; patent specifications and drawings; patent correspondence; and printed patents related to gunpowder.
Frederic J. LeMaistre business records
Frederick J. LeMaistre (1879-1944) was a chemical engineer employed by the E.I. du Pont de Nemours Powder Company at its Eastern Laboratory for fourteen years. This collection consists of ten volumes; seven are LeMaistre's laboratory notebooks documenting his work on nitrates, nitroglycerin, artificial silk (rayon), pyralin, and solvents. Also included are two souvenir logbooks of tours by the American Institute of Chemical Engineers and one Niagara Oil Company of Philadelphia cashbook.
George Levitt laboratory notebooks
George Levitt (1925-), a DuPont Company chemist working at the Experimental Station, discovered sulfonylurea (SU) herbicides in 1976 after two decades of experimentation. This collection consists of six of Levitt's laboratory notebooks documenting milestones in herbicide discovery.
Lab notebooks, 1924-2000
Most notebooks are highly technical and difficult to follow without subject expertise. However, researchers sometimes inserted reports, correspondence, or meeting records into the books. More frequent are printouts, charts, and photographs pasted onto the pages.
As notebook titles are often incomplete or nonexistent, researchers studying a specific technology should consult progress reports (Record group 27) and technical reports (2464.69) to discover the names of the scientists involved.
Information about some missing notebooks can be found in the card index maintained by the Research Library (see Record group 3, Series XII).
Notebooks with the prefix “G” (for government) were used for classified government contract work. They were stored separately until the restriction expired (usually five years or less).
Notebooks with the prefix “P” (for Princeton) were introduced in 1944 and were largely phased out by the end of 1954. Instead of being issued numbered bound notebooks, researchers turned in papers to be bound together and numbered. As a result, these notebooks often contain a wider range of materials, including correspondence, reports, and meeting records. Particularly valuable are the notebooks of Edward W. Herold, Harold B. Law, Rolf W. Peter, and Robert P. Stone.
Some notebooks were given the prefix “N” (for new?) starting in the early 1980s, but the reason is unclear. Patent disclosure notebooks, used during the 1930s and early 1940s, are also included in this record group. Finally, some scientists turned in notebooks not issued by RCA.
Laboratory notebooks, diaries, and appointment calendars, 1880-1933
The Elmer Sperry papers contain a complete record of his published patents and his laboratory notebooks. These notebooks, which do have some gaps, can be used to trace the evolution of Elmer Sperry's approach to arc lighting, street railways, electrochemistry, gyroscopic technology, internal combustion engines, and the technological problems he encountered with each of these projects. Sperry was very articulate in his diaries and explored a variety of technological and scientific issues in them. It is evident that he drew on the work of a number of academic physicists and mathematicians and tried to apply their insights to experimental problems. Sperry's diaries contain a large number of sketches which reflect an appreciation of modern science. However, the diaries also show that in many ways Sperry was a nineteenth-century artist-engineer rather than a modern scientist whose insights are based on mathematical models.
Oliver M. Hayden papers
Oliver M. Hayden (1893-1991) was a chemist who specialized in rubber and worked for E.I. du Pont de Nemours & Company as manager of the laboratory where he was part of the team that developed Neoprene. His papers document his work on the Neoprene project, the activities of the Rubber Chemicals Division, and a draft of an oral history interview.
RCA/Thomson Lancaster records
The Radio Corporation of America (RCA)’s Picture Tube Division, later known as the Video Component and Display Division, was headquartered at a research and production facility in Lancaster, Pennsylvania. In 1987, the French firm Thomson Consumer Electronics acquired RCA’s consumer electronics business, including the Lancaster plant, and operated the facility until Thomson shut down its consumer electronics operations in 2005. Materials in the collection document a diverse array of activities at the RCA/Thomson Lancaster plant between the facility’s early days of operation and its closure. Corporate memoranda, correspondence, product technical data, photographs, and audiovisual materials trace the development of RCA/Thomson’s picture tube product line. Corporate publications chronicle major moments in company history.
Roy J. Plunkett laboratory notebook
Roy J. Plunkett (1910-1994) was the discoverer of Teflon, while working as a chemist at the DuPont Company. Plunkett's laboratory notebook documents the discovery of Teflon at DuPont's Jackson Laboratory in 1938. The notebook documents the experiments that led to the effective control of the rapid and explosive polymerization of tetrafluoroethylene gas into a solid polymer.
Wallis G. Hines notes and procedures for use in the azide laboratory
Wallis Gartside Hines (1919-2014) was a chemical engineer employed at the Kankakee Ordnance Works from 1942 to 1943, a war plant of E.I. du Pont de Nemours & Company located south of Joliet, Illinois. His notes describe the steps to be followed in the manufacture and refining of sodium and lead azide and for the laboratory analysis necessary for quality control.
