She was also responsible for selecting Frank Lloyd Wright to design the current Guggenheim museum, which is now known as a modernist icon in New York City.

[5] She then attended the Académie Julian in Paris from 1909 until 1910, where she received traditional training in landscape, portraiture, genre and history painting.

Fortlage was the author of the foreword to the 1911 Ferdinand Hodler exhibition in Munich, which inspired Rebay greatly to pursue her interest in modern art.

[5] In March 1913, Rebay was exhibited alongside Archipenko, Brâncuși, Chagall, Robert Delaunay, Gleizes, Diego Rivera and Otto van Rees [nl] at the Salon des Indépendants in Paris.

This meeting was extremely influential upon Rebay's artistic taste, since it was through Arp that she was introduced to the non-objective modern art works of Kandinsky, Klee, Franz Marc, Chagall and Rudolf Bauer.

[1] These purchases later founded the basis of the Solomon R. Guggenheim Foundation's Museum of Non-Objective Painting, which opened in 1939 in a showroom located at 24 East 54th Street.

[9] In June 1943, Rebay wrote to the noted architect Frank Lloyd Wright to commission a "museum-temple" to house the growing collection.

[13] Embittered, Rebay retreated from public life and spent her final years at her estate in Westport, Connecticut.
