During this same period she was elected as a member of the prestigious photographic associations: the Linked Ring in London[2] and Alfred Stieglitz’s Photo-Secession in New York.

[1] In 1904 she stopped working to care for her ailing husband, and after his death a year later she devoted herself to managing the family’s finances for a brief period.

She then traveled throughout Europe with Cassatt and Gertrude Stein, collecting more art and living a highly glamorous lifestyle among artists, musicians and writers.

Added by the advice of Cassatt, she began to collect early Impressionist paintings by Edgar Degas, Édouard Manet and others.

Under the guidance of Stieglitz, she also collected modernist paintings by Maurice Prendergast, Arthur B. Davies, Paul Cézanne, Georges Braque and Henri Matisse.
