French architect. A pupil of J. -F. Blondel and Soufflot, he supervised the erection of some of Ledoux's Barrières around Paris from 1785, and designed the hôtel and gallery for Elisabeth Vigée-Lebrun (1755–1842), the celebrated portrait-painter (1784–6). He became architect to the Louvre, Paris, in 1798, rendering parts of it suitably magnificent to provide a setting for the treasures looted by Napoleon from the rest of Europe, and was succeeded by Percier and Fontaine (1805). His main claim to fame was his association with Chalgrin in the early designs of the Arc de Triomphe de l'Étoile, Paris (1805–6—engraved by L. -M. Normand), but he also contributed to works at the Bibliothèque Nationale and the Opéra, little of which has survived.
