(Charlotte) Béatrice de Rothschild, Baroness Maurice Ephrussi (1864-1934)
Charlotte Béatrice de Rothschild was the daughter of Leonora and sister of Bettina. She married Baron Maurice Ephrussi in 1883. Béatrice was attracted to the South of France because of the casino at Monte Carlo (so it is believed), Béatrice conceived the plan to construct the Villa Ile de France at Saint Jean Cap Ferrat, which she had carried out to perfection. The completed villa formed the backdrop for her art collections, some inherited from her father. Cap Ferrat was bequeathed to the Academy of Fine Arts and as The Musée Ephrussi Rothschild preserved the name of Béatrice's husband together with her own.
The Rothschild Archive holds no private papers of Béatrice, with the exception of a few files in the Moscow Papers (58 series), largely concerning routine matters relating to the gardens of the Villa Ile de France.
