Moïse de Camondo, a member of a wealthy clan of Sephardi merchants originating in Istanbul, settled in Paris in the 1870s with other members of his family. After his death in 1935, his home—which he filled with fashionable 18th-century antiques—became a museum that still operates today as an unintended monument to a very particular slice of French-Jewish history. Christina Sztajnkrycer writes:
The [neighborhood where the Comondos settled, known as the] plaine Monceau, is a more recent part of Paris, annexed to the city in 1860. . . . Before annexation, Emile and Isaac Pereire, having “made their fortunes as financiers, railroad-builders, and property magnates, creating colossal developments of hotels and department stores,” purchased the plaine Monceau with the park in the center and started to develop the surrounding area. These two Sephardi brothers from Bordeaux, also creators of the upscale neighborhood surrounding the Opéra Garnier and the Hôtel de la Paix in Paris, dreamed of a luxurious future for this soon-to-be elite neighborhood. . . .
[T]he Pereire brothers were not just savvy investors with a taste for luxury, they also knew how to attract and convince the wealthiest Jews of France, Europe, and the Mediterranean basin to come live in the plaine Monceau along with many other members of Parisian high society. The outcome of the Pereires’ vision was “an unprecedented mixture of nobility of the ancien régime and empire, Jewish aristocracy, high-society Protestants, [and] members of the rich industrial and financial bourgeoisie.”
