Both Sabusawa and Michener were supporters of the
1956 Hungarian Revolution against the USSR. They made their home in
Vienna a safe haven for refugees created by the conflict. This experience would influence Michener's novel,
The Bridge at Andau, 1957. Sabusawa spoke out in support of American-Japanese marriages in the 1950s. She urged her husband not to run for Congress as a Democrat in 1962, but nevertheless supported him when he did. Sabusawa was encouraged and helped in the research of some of Michener's novels, such as,
The Bridge at Andau,
Hawaii, and
The Source. Michener also wrote
Centennial, written in 1974, which was later produced into a miniseries by the same name. It was filmed in part at
Bent's Fort, close to Sabusawa's hometown of
Las Animas, Colorado. Together with her husband, Sabusawa was involved with charitable donations, with main fields of their philanthropy being art and higher education. Notably, she established the Mari Sabusawa Michener Endowment, which funded all the educational programs at the
James A. Michener Art Museum in
Doylestown, Pennsylvania. ==Death==
