One of the scholars who accompanied Napoleon to Egypt in 1798, he was involved in the preparation of the great Description de l'Égypte, one of the most important source-books of C19 Egyptology. He designed the exquisite surtout of the Sèvres Service Égyptien (1811–12) representing the Kiosk at Philae, obelisks from Luxor, and the pylon-towers of the temple at Edfu. He also designed many of the medals struck to glorify episodes in the history of the Empire of Napoleon I. In 1802, with Percier and Fontaine, he was involved in the design of Malmaison, and, with Gondouin, was responsible for the Colonne Vendôme, Paris (1806–10), based on the Trajanic exemplar. He prepared the earliest designs for the Church of St-Vincent-de-Paul, Paris (1824), in the style of Chalgrin's St-Philippe-du-Roule (1768–84). He was Hittorff's father-in-law.
