Delaunay traveled to Berlin in January 1913 for an exhibition of his work at Galerie Der Sturm. On their way back to Paris, the two stayed with August Macke in Bonn, where Macke introduced them to Max Ernst. When his painting La ville de Paris was rejected by the Armory Show as being too big he instructed Samuel Halpert to remove all his works from the show. Spanish and Portuguese years (1914–1920) At the outbreak of the First World War in 1914 Sonia and Robert were staying in Fontarabie in Spain. They decided not to return to France and settled in Madrid. In August 1915 they moved to Portugal where they shared a home with Samuel Halpert and Eduardo Viana. With Viana and their friends Amadeo de Souza Cardoso (whom the Delaunays had already met in Paris) and José de Almada Negreiros they discussed an artistic partnership. First declared a deserter, Robert was declared unfit for military duty at the French consulate in Vigo on 23 June 1916. The Russian Revolution brought an end to the financial support Sonia received from her family in Russia, and a different source of income was needed. In 1917 the Delaunays met Sergei Diaghilev in Madrid. Robert designed the stage for his production of Cleopatra (costume design by Sonia Delaunay). Robert Delaunay illustrates Tour Eiffel for Vicente Huidobro. Paul Poiret refused a business partnership with Sonia in 1920, citing as one of the reasons her marriage to a deserter. The Der Sturm gallery in Berlin showed works by Sonia and Robert from their Portuguese period the same year. Return to Paris and later life (1921–1941) After the war, in 1921, they returned to Paris. Delaunay continued to work in both figurative and abstract themes, with a brief stint into Surrealism. Delaunay met André Breton and Tristan Tzara, who introduced him to both Dadaists and Surrealists. 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 of cancer on 25 October 1941 in Montpellier at the age of 56. His body was reburied in 1952 in Gambais. Gallery Museum collections Robert Delaunay's works can be found in museums and
