Noémie de Rothschild was born as Noémie Halphen on 29 June 1888 in Paris, France to Jules Halphen and Marie Hermine Rodrigues-Péreire.[1] She was the granddaughter of financier Eugène Péreire of the Sephardic-Jewish Péreire family of Portugal who were banking rivals of the Rothschilds.
Rothschild turned her hôtel particulier in Paris into a hospital during World War I.[1] In 1916, she decided to develop a ski resort in France to avoid having to holiday alongside the Germans in St. Moritz, Switzerland.[1] [2] By 1919, she founded Société Française des Hôtels de Montagne.[1] Rothschild developed the Domaine du Mont d'Arbois, a luxury hotel in Mont d'Arbois near Megève in Haute-Savoie.[3] It was completed in 1921.[1]
