Gabriela and Mathieu Sismann’s passion for Old Master Sculpture led them to found their gallery in 1994 in Paris. Their international standing gallery provides a large selection of Old Master Sculpture. It has gained widespread renown as the only exhibition space devoted to a whole spectrum of European dating from the Middle Ages, the Renaissance, the Classical and the Baroque periods and the 18th century. Driven by their instinct for fine pieces and their fascination with the spiritual aspect of the creative process, their acquisitions reflect a quest for rare , unknown or forgotten works of art.
Every Autumn the GALERIE SISMANN publishes a catalogue presenting its major discoveries and attributions, organizes local exhibitions and participates in international exhibitions (BRAFA, Masterpiece London, La Biennale Paris).

GALERIE SISMANN has contributed to the expansion of important private collections and of prestigious institutions across the world which include the Metropolitan Museum of Art (New York), the Louvre Museum (Paris), the Musée National du Moyen Âge (Paris), the Musée National de la Renaissance (Ecouen), the Palais des Beaux-Arts de Lille, the MuseĢe des Beaux-Arts de Strasbourg, the Fondation Lambert (Avignon), the Tassenmuseum (Amsterdam), the Katoen Natie Art Foundation (Anvers), Le Palais Fesch - Musée de Beaux-Arts (Ajaccio) ...
