French architect, part of a family of architects. He was the son of Antoine Laurent Thomas Vaudoyer, father of Alfred Lambert Vaudoyer (1846-1917), and grandfather of Léon Jean Georges Vaudoyer (b. 1866). In 1819, Léon Vaudoyer entered Antoine Vaudoyer and Louis Hippolyte Lebas's atelier, as well as the Ecole des Beaux-Arts in Paris. He won the second prize of the concours de Rome in 1824, and the Grand Prix in 1826. In 1832, he began work under Lebas and opened an atelier. After his father's death in 1846, he took over his atelier and his most important commission, the conversion of the Priory of Saint Martin des Champs into the Conservatoire des Arts et Métiers. He was the architect of the Cathedral of Marseille, from 1855 until his death. //
