In 1948, Le Chevallier organized the Centre d’Art sacré in collaboration with Maurice Rocher and has been a lecturer in stained glass windows at the École supérieure des Beaux-Arts.
He used industrial materials to create lamps designed for individuals in general or to be used in well-defined architectural projects.
Le Chevallier also created a number of stained glass windows in the studio of Louis Barillet, 15 Square de Vergennes, for the French Pavilion at the Exposition international des Arts décoratifs de 1925 in Paris.
