His son, Alfred Victor du Pont, was one of founding fathers of the alpha (first) chapter of Phi Kappa Sigma fraternity on October 19, 1850, affiliated with University of Pennsylvania,[1] which is a charter member of the North American Interfraternity Conference.

He came to the United States in 1800 as an infant and grew up around the gunpowder mills founded by his father on the Brandywine Creek in Delaware.

Du Pont married American Margaretta Elizabeth "Molly" La Motte (or Lammot) in 1824; they had seven children.

In 1818, du Pont returned home to help his father rebuild the gunpowder company after an explosion that killed 33 people and injured his mother.

It was a difficult role for him, and after leading the company through a recovery from a disastrous mill explosion in 1847, he retired in poor health in 1850.
