Jacques-Félix Duban was the brother-in-law of François Debret. He won the Prix de Rome in 1823 and spent five years in Italy. It was on the recommendation of Delaroche that Duban received the commission from the Ecole des Beaux-Arts to design its new wings. He oversaw the restoration of Sainte Chapelle in Paris and the Château de Blois. Duban also worked at the Louvre.
