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.
