Roger-Henri Expert

The son of a merchant, Expert first studied painting at the École des beaux-arts in Bordeaux, then from 1906 attended the École nationale supérieure des Beaux-Arts in Paris, where he studied under Gaston Redon and Gustave Umbdenstock.

In 1921 he accepted a position as Architecte des Bâtiments civils et palais nationaux (official architect of national structures), responsible for the maintenance of the Louvre Palace, Gobelins Manufactory, the Panthéon, as well as new projects for embassies, fair pavilions and other government commissions through the 1950s.

Stylistically Expert worked in a simplified classicism tending towards Art Deco—his Tourism Pavilion for the 1925 International Exhibition of Hydropower and Tourism in Grenoble is an early and uncharacteristic showy example.

(His dramatic floodlighting for the 1937 Paris Exposition, seen by Albert Speer, preceded Speer's "cathedral of light" at the Festliches Nürnberg by a few months.
