Gordon Derby Patterson (1897-1982) was a chemist who spent nearly forty years with the Central Research Department (formerly the Chemical Department) at the E.I. du Pont de Nemours & Company, a chemical company more commonly referred to as the DuPont Company. In addition to his early work in pigments and rayon, Patterson directed research in high-energy radiation generators, radioactive tracer techniques, nuclear magnetic resonance, electron microscopy, and absorption spectroscopy. His papers provide extensive documentation for these projects, giving particular emphasis on ideas and suggestions for possible areas of exploration. In addition, there are administrative records, including outlines for research directors and the Steering Committee reviewing the status of current and proposed projects, as well as technical reference materials, such as summary reports, scientific papers, and literature reviews.
