[6][7] In 1928, she moved to New York City and began collecting works by modern abstract artists such as Paul Klee, Piet Mondrian, Stuart Davis, Jean Arp, and Giorgio de Chirico.
[8][9] On her return to Seattle in 1942, she began promoting advanced contemporary art, which had not previously been widely exhibited in the Pacific Northwest.
[14][15][16] She was an avid supporter of Northwest-based artists such as Guy Anderson, Kenneth Callahan, Morris Graves, Paul Horiuchi, Philip McCracken, Mark Tobey, and George Tsutakawa, and played an important role in bringing national attention to the 'Northwest School'.
[17][18] Her gallery was the first in North America to mount shows by Japanese artist Yayoi Kusama[19][20] and French artist/poet Henri Michaux,[21][22] and she was an early exhibitor of works by Sam Francis,[23][24] Paul Jenkins,[25][26] Karl Otto Götz,[27] John Franklin Koenig,[28] and many others.
In 1953, largely as a result of Dusanne's efforts, Life magazine ran a major article on the "Mystic Painters of the Northwest", which propelled Tobey, Graves, Callahan, and Anderson to national prominence.
