Iler (1909-1985) describing the department's fundamental research program on inorganic chemistry.

E.I. du Pont de Nemours & Company is a chemical company, commonly referred to as the DuPont Company. It manufactured paints, dyes, and photographic products, and focused on applied research. This collection consists of materials related to patents and patent research. It includes patent proposal logs and patent search files from several DuPont Company departments related to photographic film and electronic products. The departments include: Photo Products, Electrochemical (Elchem), Electronics, Imaging Systems, and Photosystems and Electronics Department. This collection would be useful for examining research trends and patented product development.

E.I. du Pont de Nemours & Company’s R. & H. Chemicals Department manufactured and sold peroxides, cyanide of sodium, formaldehyde, trychloretheline, tin oxide, and polyvinyl alcohol. The department was formed in 1933 as a result of the 1930 acquisition of the Roessler & Hasslacher Chemical Company, which operated a plant in Niagara Falls, New York. The records primarily consist of reports on experimentations with various insecticides, pesticides, preservatives, and other forms of pest and disease-control applied to the farming and agricultural industries.

E. I. du Pont de Nemours & Co. (alternatively referred to as the DuPont Company, or simply DuPont) was reincorporated on February 26, 1902, as successor to the partnership Eleuthère Irénée "E.I." du Pont (1771-1834) and his father Pierre Samuel "P.S." du Pont de Nemours (1739-1817) had organized in 1801 for the purpose of manufacturing gunpowder in the United States. During the twentieth century, the company diversified beyond gunpowder and explosives into the broader chemicals industry. The twentieth-century records (dating up to 1972) of E.I. du Pont de Nemours & Co. document the transformation of the company into a modern, centrally administered industrial giant. The collection, however, is not comprehensive for the period, and any company collections received after 1972 were accessioned and processed separately by Hagley Museum and Library.

H.E. Schroeder (1915-2009) was a research chemist who spent most of his career with E.I. du Pont de Nemours & Company. His papers consist of documents and memorabilia covering his family and professional life.
