In 1930 Callahan married Margaret Bundy, who was a co-editor of
Town Crier, a literary magazine published in Seattle between 1912 and 1937. The Callahans developed friendships with Dr. Richard Fuller (founder of the Seattle Art Museum), Mark Tobey, Morris Graves, and other progressive-minded artists. Their home became a meeting-place for Seattle's arts community, including prominent Japanese-American artists
Kenjiro Nomura and
Kamekichi Tokita, and many others. In 1933 - at age 27 - he gained national recognition with the inclusion of some of his paintings in the First Biennial Exhibition of Contemporary Art at the
Whitney Museum, in New York. The same year he began his twenty-year tenure with SAM, when it opened its new building in Seattle's
Volunteer Park. Over the next two decades he curated exhibitions at SAM, wrote a weekly arts column for
The Seattle Times, and took trips to Europe and Latin America; his main focus, however, remained his painting. He had numerous exhibitions, was commissioned to do several murals (including
post office murals for the
Section of Painting and Sculpture in
Anacortes and
Centralia, Washington and
Rugby, North Dakota), and helped form the Group of Twelve, an "independent salon" of Northwest artists. In the late 1930s he and his wife began spending much of their time in the Robe Valley area of the
North Cascades mountains; during the Second World War he spent summers as a U.S. Forest Service fire lookout in the Cascades. Over time, figurative elements - men, horses, trees, insects - disappeared from his work, in favor of pure abstraction, but still, said Callahan, "It is nature, with its unlimited varied form, structure, and color that constitutes the vital living force from which art must basically stem." While Callahan enjoyed his status as a respected artist, the increasingly abstract style of his painting did not lend itself to ready sales. He supplemented his income with occasional teaching jobs at various colleges, and in 1954 applied for and received a Guggenheim Fellowship. In 1961 Margaret died of cancer; two years later his summer home/studio near the
Stillaguamish River burned down while he was in Europe, with the loss of many paintings by both himself and friends. He married Beth Inge Gotfredsen in 1964, and they moved to
Long Beach, Washington, on the Pacific coast. ==Later years==
