Charles J. Pedersen (1904-1989) was a research chemist with E.I. du Pont de Nemours & Company who spent most of his career at the Jackson Laboratory in Deepwater, New Jersey, and the Elastomer Chemicals Department in Wilmington, Delaware. This collection consists of two laboratory notebooks from Jackson Laboratory from 1956.

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.

A collection of bulletins and reports from the library of DuPont's Jackson Laboratory. Most were generated by the Organic Chemicals Department, which operated Jackson Laboratory, but others come from other DuPont Departments and their laboratories.

Jackson Laboratory was a dye works established in 1917 by E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont Company. The records of the Jackson Laboratory are fragmentary in nature and divided into two series that document cutting-edge research projects conducted by DuPont scientists, primarily in the 1920s and 1930s. Under the direction of Fletcher B. Holmes (1877-1961) and W. S. Calcott (1892-1952), the processes for producing many important products, including neoprene synthetic rubber, were perfected during this period.

John M. Tinker (1897-1974) was the director of Jackson Laboratory, the main research unit of the Organic Chemicals Department of E.I. du Pont de Nemours & Company, from 1943 to 1962. After his retirement, he joined the U.S. Foreign Service and worked for three years as the science attaché at the U.S. Embassy in Karachi, Pakistan. This small collection of Tinker's papers is related to both his time at Jackson Laboratory and his work for the U.S. government.
