Marthe Donas (1885–1967) was an important figure in early Belgian abstraction.She fled to the Netherlands after the outbreak of World War I. She studied stained-glass making in Dublin and moved to Paris in 1916. There Donas became acquainted with Cubist painters and joined La Section d’Or. Finding it difficult to gain serious critical attention as a female painter, she often went by pseudonyms, calling herself “Tour” Donas or “Tour D’Onasky.” Donas exhibited with the Peataux Group in Paris in 1920. In spite of a growing appreciation for her work in the 1920s, Donas could not support herself as a painter. After a long hiatus, she returned to painting in 1949, and exhibited in Brussels, Antwerp, and Berlin through the ’50s and ’60s.
