settled with friends in Portugal for the duration of the conflict. During this period, the couple
took on several jobs designing costumes for the Madrid Opera, and Sonia Delaunay started a
fashion design business. After the war, in 1921, they returned to Paris. Delaunay continued to
work in a mostly abstract style. During the 1937 World Fair in Paris, Delaunay participated in
the design of the railway and air travel pavilions. When World War II erupted, the Delaunays
moved to the Auvergne, in an effort to avoid the invading German forces. Suffering from
cancer, Delaunay was unable to endure being moved around, and his health deteriorated. He
died from cancer on 25 October 1941 in Montpellier.
