The Prix de Rome in 1806 launched the career of Louis-Hippolyte Lebas, a figure central to the development of 19th-century French architectural practice. Operating from Paris, he adhered to a rational, austere Neoclassical style that emphasized structural clarity, bridging the gap between the monumental designs favored during the Napoleonic era and the architectural pedagogical shifts of the mid-1800s.
Professional Foundations and Collaborations
Lebas received his formal education at the Collège Sainte-Barbe and the French Academy in Rome. Early in his career, he worked within the atelier of Percier and Fontaine, who served as architects to Napoleon. Following the exile of the emperor, Lebas maintained a close professional relationship with Pierre François Léonard Fontaine. Under this partnership, he oversaw the construction of the Chapelle Expiatoire between 1816 and 1824, a project intended to memorialize Louis XVI and Marie Antoinette. Additionally, he assisted Éloi Labarre in the final stages of the Palais Brongniart, which served as the seat of the Paris Bourse, between 1813 and 1826.

Among his primary individual commissions, the church of Notre-Dame-de-Lorette stands as his most recognizable work in Paris. Construction on this structure began in 1823 and reached completion in 1836. During this same period, Lebas engaged with institutional design, notably building the Petite Roquette prison from 1826 to 1836. This project introduced the panoptic prison model to France, prioritizing surveillance and internal order. The structure remained in use until its demolition in 1974.
Academic Influence and Art History
Beyond his work as a practitioner, Lebas held a significant role at the Beaux-Arts de Paris, where he served as a professor of the History of Architecture from 1840 to 1863. He applied the art-historical methodologies established by Johann Joachim Winckelmann to his academic instruction. Through this role, he exerted influence over multiple generations of French architects, shifting the focus of architectural education toward a systematic analysis of historical precedent.
