In France, style and refinement are tantamount to an art form. At the Musée Nissim de Camondo, a Paris mansion built between 1911 and 1914 in the style of the Petit Trianon at Versailles, the rooms are dedicated to 18th-century decorative arts—specifically objects and furniture from the reigns of Louis XV and Louis XVI. The collection was assembled by Moïse de Camondo, a Sephardic Jew from a prominent Constantinople banking family; he grew up in Paris, where he too became a banker. De Camondo died in 1935. He had outlived his son, Nissim, who was killed in W.W. I, but was survived by his daughter, Béatrice. She and her family, however, died in Auschwitz. There the family line ended, but its name lives on here. —E.C.
