Jules Cavaillès was a master at expressing the joie de vivre in his paintings. He grows up in Carmaux and is first a technical draftsman at the Carmaux Mining Company.
From 1922, Jules Cavaillès studied at the prestigious "Académie Julian" in Paris, where Henri Matisse had also been a student about 30 years previously. He admired the Fauvists, especially Derain, Vlaminck, Braque and Matisse. With his wife Rose, he moves to the Parisian district of La Ruche, where previously artists such as Soutine, Modigliani, Chagall and Zadkine lived. To buy the expensive art supplies, he runs a grocery store with his wife. For years, Cavaillès shares a studio with his friend and artist colleague Roger Limouse. At the beginning of his career he studies the old masters in the Louvre.
In 1936, Cavaillès received a scholarship from the Fondation Blumenthal, which gave him more and more publicity: on the occasion of the "Exposition Internationale des Arts et Métiers" in 1937, he was commissioned to decorate the Pavillon des Languedoc. In the same year Cavaillès first solo exhibition takes place in the "Galerie Druet" in Paris. In 1938 he receives a professorship at the "École nationale des Arts décoratifs". During the Second World War he is an active member of the Resistance. After the war, Cavaillès worked conservatively on the "Musée des Augustins" in Toulouse, but soon resumed teaching as a professor in Paris.
In 1948, the artist is represented at the Venice Biennale. He has been exhibiting his works internationally since 1937. Alongside France (Paris, Nice), he is also present in Finland (Helsinki), England (London), Germany (Cologne) and the USA (New York).
His colourful and joyful life pictures characterize his entire oeuvre. With this intention Cavaillès belongs to the artist group "La Réalité Poétique". He loved happy pictures that conjure up the joys of life: the view through open windows of sunny harbor scenes, the lush landscape, naked women, colorful flowers in decorative interiors and even lobsters.
