Henry Miller (1845-1926) was first employed at the Brandywine Works of E.I. du Pont de Nemours & Company. In 1922, he was one of the oldest surviving employees when he was interviewed by Alfred I. du Pont (1864-1935). In the interview, Miller describes the layout of the Brandywine Works as it changed over time, as well as the various apparatus and processes used in the manufacture of gunpowder and its constituent ingredients.

The collection comprises approximately 200 oral history interviews with 152 individuals conducted by museum staff between 1954 and 1990. The majority of the individuals interviewed had either worked at the DuPont Company powder yards on Brandywine Creek during the yards’ final decades of operation or had lived in the surrounding communities, although the collection also includes interviews with those who worked in other local industries. The interviews are largely biographical in nature covering a period from about 1900 to 1960 and address a wide range of subjects relating to daily life and work in the Brandywine Valley.
