Projet de cénotaphe à Isaac Newton - Vue en élévation. 1784.
Étienne-Louis Boullée (February 12, 1728 – February 4, 1799) was a French neoclassical architect whose work greatly influenced contemporary architects and is still influential today.
Born in Paris, he studied under Jacques-François Blondel, Germain Boffrand and Jean-Laurent Le Geay, from whom he learned the mainstream French Classical architecture in the 17th and 18th century and the Neoclassicism that evolved after the mid century. He was elected to the Académie Royale d’Architecture in 1762 and became chief architect to Frederick II of Prussia, a largely honorary title. He designed a number of private houses from 1762 to 1778, though most of these no longer exist; notable survivors include the Hôtel Alexandre and Hôtel de Brunoy, both in Paris. Together with Claude Nicolas Ledoux he was one of the most influential figures of French neoclassical architecture.
