(b Paris, 1889; d Paris, 1956). French architect. He studied architecture at the Ecole des Beaux-Arts in Paris and then took the course in Monuments Historiques. Influenced by his friendship with André Lurçat, he adhered to contemporary architectural theories throughout the 1920s. In 1926 he designed the Wanda Landowska Concert Hall as well as a number of private houses in which he used a metal framework as the basis of his structures. He also produced theoretical plans for workshop and studio buildings and for an overall reorganization of the architecture of Paris. He was one of the foremost members of the French group at CIAM. In the early 1930s Moreux began to express doubts about what he referred to as ‘tubism’ and to distance himself from the ideals of the day. Thereafter, Moreux rediscovered the attractions of traditional forms and materials, which he used in a number of houses in Paris (often reinterpreting the architecture of buildings designed in a functionalist spirit, such as the Hefferlin house belonging to Lurçat, which Moreux transformed into a Spanish-style caprice in 1937).
