Continuity of the du Pont family's participation in the business is symbolized above. Four great-great-grandsons of the founder stand by one of the early mills along the Brandywine. These du Ponts four of the youngest members of the family now in the company, are left to right: James Q. of Public Relations Department; E. Paul, Jr., Experimental Station; Irénée, Jr., Washington Works, West Virginia; and Reynolds, of the Edge Moor, Delaware, pigments plant.
Two great-great grandsons of Eleuthère Irénée du Pont look at the marker dedicated July 18, the DuPont Company's 150th anniversary, on Brandywine Creek, near Wilmington, Delaware. The du Ponts, two of the youngest members of the family now in the company, are, left, E. Paul, Jr., and Reynolds du Pont. The marker is a huge granite millstone ordered from France by E.I. du Pont in 1801. Its function was to grind, with water, the ingredients of black powder-charcoal, sulfur and saltpeter.
