After the Errázuriz settled in Paris, they became friends with many in the same circle as the Subercaseauxes: the American heiress Winnareta Singer; the French composer Gabriel Fauré; French painters Joseph Roger-Jourdain, Ernest Duez, and Paul Helleu; and the Italian artist Giovanni Boldini. Eugenia was an avid supporter of the arts and she sought out artists, supporting both Stravinsky and Diaghilev at one point, and establishing friendships with such noted writers and musicians as W. R. Sickert, Baron de Meyer, Jean Cocteau, and Cecil Beaton.
