Modern Art of two brothers
Here is the bio of the younger brother: "Jean Dufy was a French Art Deco painter best known for his colorful depictions of post-war Parisian society, notably Jazz musicians who arrived with American soldiers. He was born on March 12, 1888 in La Havre, France as the brother of the well-known French Fauvist painter Raoul Dufy, who would serve as a mentor to Dufy throughout his career. Though he had no formal training, he decided to become a painter after seeing a gallery exhibition of Modern Art in La Havre—he had his first show in 1914 at Galerie Berthe Weill. For almost 30 years, Dufy was employed at a porcelain manufacturer hand-painting decorative designs of animals and flowers, for which he would win a gold medal at the 1925 L’exposition Internationale des Arts Décoratifs—the very exhibition where the term Art Deco was first coined. Dufy was for a time the next-door neighbor to Georges Braque, who would encourage the younger artist to experiment with Cubism. He died on May 12, 1964 in La Boissière, France."
