A company town was set up about a mile east of the explosives manufacturing facility. By 1909, the village had two houses for the plant managers and 58 houses for the workers, which increased to over 100 houses by the end of 1917. The village was re-designated as the town of DuPont on March 26, 1912, but it was not officially incorporated as a town until 1951, when the company started selling the houses to the employees. The original company town, roughly bounded by Santa Cruz St, Penniman St, Brandywine Ave, and DuPont Ave, was added to the National Register of Historic Places as the DuPont Village Historic District in 1987.
