E.I. du Pont de Nemours & Company was established in 1802 by Pierre Samuel du Pont de Nemours (1739-1817) and his son Éleuthère Irénée du Pont (1771-1834). The du Ponts purchased a mill site on the banks of the Brandywine River just North of Wilmington, Delaware. The pulp keg mill, after the powder yards closed, was used for record storage by the DuPont Company. (Currently, it is a Hagley Museum and Library property, the Hall of Records.) In 1903, the DuPont Company's Executive Committee established the Experimental Station, a research facility located on the banks of the Brandywine Creek across from the du Pont's first black powder works. This collection consists of photographs and negatives from the DuPont Company's Secretary's Department showing the Hall of Records at various times and one aerial view of the Experimental Station.

Louis R. Wonderly (1931-) worked in the E.I. du Pont de Nemours & Company Secretary's Department for thirty years. E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont Company. This small collection of Louis Wonderly's papers provides a glimpse into the secretary's work at the DuPont Company. It would be of interest to those researching the DuPont Company's upper-level management and operations from the 1920s through the 1970s.
