The DuPont Company's Chestnut Run Laboratories were opened in 1954 near Wilmington, Delaware. The first laboratory was the Textile Research Laboratory whose purpose was to test the effects of normal wear and tear on DuPont's line of synthetic fibers and fabrics. This collection consists of eight albums of photographs showing laboratories, fabrication equipment, testing equipment dating to the mid-1950s, and personnel photographs from the late-1980s.
