After his work was seen by Louis Aragon and Salvador Dalí, Trouille was declared a Surrealist by André Breton - a label Trouille accepted only as a way of gaining exposure, not having any real sympathy with the Surrealism movement.
The simple style and lurid colouring of Trouille's paintings echo the lithographic posters used in advertising in the first half of the 20th Century.Camille Clovis Trouille, was born on 24 October 1889, in Amiens, France. He worked as Sunday painter and a restorer and decorator of department store mannequins, and trained at the École des Beaux-Arts from 1905 to 1910. He died on 24 September 1975 in Paris.
Paul Delvaux was born on September 23, 1897, in Antheit, Belgium. At the Academie Royale des Beaux-Arts in Brussels he studied architecture from 1916 to 1917 and decorative painting from 1918 to 1919. During the early 1920s he was influenced by James Ensor and Gustave De Smet. In 1936 Delvaux shared an exhibition at the Palais des Beaux-Arts in Brussels with Rene Magritte, a fellow member of the Belgian group Les Compagnons de l'Art.
Delvaux was given solo exhibitions in 1938 at the Palais des Beaux-Arts, Brussels, and the London Gallery, the latter organized by E. L. T. Mesens and Roland Penrose. That same year he participated in the Exposition internationale du surrealisme at the Galerie des Beaux-Arts in Paris, organized by Andre Breton and Paul Eluard, and an exhibition of the same title at the Galerie Robert in Amsterdam. The artist visited Italy in 1938 and 1939. His first retrospective was held at the Palais des Beaux-Arts in Brussels in 1944-45. Delvaux executed stage designs for Jean Genet's Adame Miroire in 1947 and collaborated with Eluard on the book Poemes, peintures et dessins, published in Geneva and Paris the next year. After a brief sojourn in France in 1949, the following year he was appointed professor at the Ecole Superieure d'Art et d'Architecture in Brussels, a position he retained until 1962. From the early 1950s he executed a number of mural commissions in Belgium. About the middle of the decade Delvaux settled in Boitsfort, and in 1956 he traveled to Greece.
From 1965 to 1966 Delvaux served as president and director of the Academie Royale des Beaux-Arts of Belgium, and about this time he produced his first lithographs. Retrospectives of his work were held at the Palais des Beaux-Arts in Lille in 1965, at the Musee des Arts Decoratifs in Paris in 1969, and at the Museum Boymans-van Beuningen in Rotterdam in 1973. Also in 1973 he was awarded the Rembrandt Prize of the Johann Wolfgang Stiftung. A Delvaux retrospective was shown at the National Museum of Modern Art in Tokyo and the National Museum of Modern Art of Kyoto in 1975. In 1977 he became an associate member of the Academie des Beaux-Arts of France.
Delvaux died in Veurne, Belgium, on July 20, 1994.
