For Rebay, the non-objective was the art of the future. With no reference to nature or the material world entirely, it employed what she believed to be the creative-spiritual powers of the artist to bring forth new worlds through spatial relationships between shapes, lines, and colors. In line with the thinking of German artist Rudolf Bauer and Russian artist Wassily Kandinsky as outlined in the latter’s Concerning the Spiritual in Art (1911), Rebay believed the non-objective served as a new universal language with the potential to redeem humanity from its prevailing materialism and usher in a new spiritual future.
Earlier, in 1927, Rebay had left a successful career and her avant-garde networks in Europe that included friends Bauer, Hans Arp, Hans Richter, and the Waldens of the modernist magazine and gallery Der Sturm in search of greater opportunity in the United States. She was one of many emigrants who, during the interwar years, departed Europe for the glimmering promise of America, yet was one of few so fortunate to have quickly connected with someone of not only great financial power but an open mind. When Rebay arrived in New York, the United States was still slow in its embrace of modern art, abstraction especially. However, Guggenheim’s background in business and his own discovery of a new copper mining technique as a young boy taught him that unconventional ideas were often the very ones with the power to change the world. Thus, by 1929, Guggenheim began working with Rebay to build a collection of non-objective art. When Rebay became the founding director of the Solomon R. Guggenheim Foundation and curator of the collection in 1937, it held approximately 400 works. Two years later, in 1939, when Rebay opened its very first museum, The Museum of Non-Objective Painting (a precursor to the current Solomon R. Guggenheim Museum), the collection had nearly doubled in size. Its inaugural exhibition, The Art of Tomorrow, featured works by Kandinsky, Bauer, Rolph Scarlett, Paul Klee, László Moholy-Nagy, Maria Helena Vieira da Silva, and Rebay herself, among others. As she wrote in the corresponding catalogue, the museum was a utopia “come true,” bringing forth “the bright millennium of cooperation and spirituality with its love for order and rhythm.”
