After a life long dedication to seizing the magic of Paris during its transition from the romantic Belle Epoque to the modern, twentieth century metropolis as we know it, Cortès has left the world a legacy of master paintings. Now found in the most prestigious collections throughout the world, his work continues to awe collectors. Cortes was an active member of the Union des Beaux-Arts de Lagny and was the Unions first president. Their inaugural exhibition was held in 1927 and Cortès continued to exhibit there until the late 1930's. During this period he received many awards, gained great notoriety and was a frequent exhibitor at the exhibition halls in Paris, including the Salon d'Automne, Salon d'Hiver, Salon de la Société Nationale de l'Horticulture and Salon des Indépendants.
