French designer, decorator, designer and painter who distinguished himself during the Art Deco period. At the International Exhibition of Modern Decorative and Industrial Arts in 1925, he exhibited a dining room that won him a Grand Prize. In 1926, Jules Leleu opened a new activity within his company: fitting out ocean liners. The Cie Générale Transatlantique commissioned him to install and decorate the reading and writing lounge on the liner "Île-de-France" - ambassador of the French "Art Deco" style to the United States. Leleu participated in the decoration of lounges on the liner "Atlantique" (1928-1930) intended for the South American lines. The fittings of this boat prefigure the liner "Normandie" of 1935. Leleu designed the installation of French and foreign embassies, and worked for Prince Pierre of Monaco, Prince Takatma Tsu of Japan, the King of Romania. He designed the French lounge of the Palais des Nations for the League of Nations in Geneva – which became the United Nations Office – preserved to this day in its original state. After the war, Maison Leleu grew even more. Among the best-known projects, we can cite that of the shipping companies for the fitting out of the buildings of their fleet or the private dining room of the Élysée Palace. In 1954, the SNCF entrusted Leleu with the fitting out of the presidential train inaugurated by President René Coty. Cie Générale Transatlantique, which undertook the construction of the liner France, entrusted Maison Leleu with the library, the reading and writing lounge and the bridge lounge. The Shah of Iran wanted to celebrate the 2500th anniversary of the Persian Empire. The design and decoration of the "camp", the setting for this celebration, spread over 64 hectares at the foot of the ruins of Persepolis, was entrusted to Maison Jansen, which for this occasion merged with Maison Leleu, founding the "Société Nouvelle Jansen". Exhibited in various museums: Musée des Arts Décoratifs, Paris Musée des Années 30, Boulogne Musée Piscine, Roubaix Metropolitan Museum of Art, New York
