Life
Life
Guillaume Tronchet studied at Beaux-Arts de Paris. The recorded working language is French. Residence is recorded at Paris. Work by Guillaume Tronchet is recorded in the collections of Smithsonian American Art Museum. Distinctions recorded are Prix de Rome, Commander of the Legion of Honour, Officier de l'Instruction publique and Knight of the Order of Agricultural Merit.
Tronchet was born in Villeneuve-sur-Lot, Lot-et-Garonne. He studied at the École des Beaux-Arts de Paris in the studio of Louis-Jules André, then in 1890 in that of Victor Laloux. Gaining his diploma in 1891, in 1892 he won the Deuxième Second Grand Prix de Rome with his design entitled "Un musée d'artillerie". For Fernand Halphen he built the château Mont-Royal at La Chapelle-en-Serval near Chantilly (Oise). After having rejected a project in the Anglo-Norman style by the architect René Sergent, then a first project in a medieval style (drawings in the collection of the Musée d'Orsay), Halphen decided on the second design, by Guillaume Tronchet: a château in the Louis XVI style celebrating hunting on the exterior and music in the interior. Built from 1907 to 1911, the building (now a hotel) was a great architectural success. Head architect of civil buildings and national palaces, in 1929 Tronchet was entrusted with the construction (in only 8 months) of a new building for the ministry of employment on place de Fontenoy in the 7th arrondissement of Paris by the minister of employment Louis Loucheur. He used the most modern materials and techniques and famous decorative artists, such as frères Martel for the sculpture and Jacques Grüber for the glass windows. Tronchet died in Nice in February 1959. His memory is perpetuated today by a foundation and, during the annual ceremony of the Académie des Beaux-Arts under the coupole of the Institut de France, this awards a prize to encourage a young artist (usually an architect).
