The son of Abraham de Camondo [1829-1889] and Régina Baruch [1833-1905], Isaac came from a family of bankers of Italian descent. In 1866 Abraham and his brother Nissam relocated from Turkey to Paris. They were a family of collectors. Isaac, who did not marry, left his substantial collection of Far-Eastern, Medieval and decorative arts, paintings and drawings, to the Louvre. Nissam's son Moïse established a museum in Paris in the name of his son Nissam, who died in World War I. Moïse's daughter Béatrice and her family, including her husband Léon Reinach and children Fanny and Betrand, all died in concentration camps during the second World War.
