[Description and dates], Box/folder number, John W. Macklem collection of DuPont Company powder yards photographs (Accession 1968.010), Hagley Museum and Library, Wilmington, DE 19807
John W. Macklem (1867-1948) began working for E.I. du Pont de Nemours & Company as an errand boy at a young age and remained
with the company his entire career. E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the
DuPont company. The company was established in 1802 by Pierre Samuel du Pont de Nemours (1739-1817) and his son Éleuthère
Irénée du Pont (1771-1834) the company began with the production of gunpowder.
Three of the photographs in this collection were taken by Pierre A. Gentieu (1842-1930), a long-term employee of the DuPont
Company who took extensive photographs of the company's Brandywine Works at the turn of the twentieth century.
The photographs depict buildings and scenes in DuPont Company explosives manufacturing plants along the Brandywine Creek near
Wilmington, Delaware, including the Eleutherian Mills (or Upper) yard, the Upper Hagley yard, and the Lower Hagley yard. Most
pictures were taken after the yards ceased operation in 1921 and the buildings were abandoned. The collection also includes
views of private residences near the yards, workers housing, a press house being demolished, Breck's Mill, and Henry Clay
Village. Three albumen photographs taken by Pierre Gentieu in 1889 depict the aftermath of an explosion.
Most of the photographs have extensive captions handwritten and signed by Macklem on reverse.
