Joseph Csaky (also written Josef Csàky, Csáky József, József Csáky and Joseph Alexandre Czaky) (Szeged, March 18, 1888 – Paris May 1, 1971) was a Hungarian avant-garde artist, sculptor, and graphic artist, best known for his early participation as a sculptor in the Cubist movement. Joseph Csaky was one of the first sculptors in Paris to apply the principles of pictorial Cubism to his art, and was a pioneer of modern sculpture. He was an active member of the Section d'Or group between 1911 and 1914, and closely associated with De Stijl and Purism throughout the 1920s.Csaky fought alongside French soldiers during World War I and in 1922 became a naturalized French citizen. He was a founding member of l'Union des Artistes modernes (UAM) in 1929. During World War II, Csaky joined forces with the French underground movement (la Résistance) in Valençay. In the late 1920s, he collaborated with some other artists in designing furniture and other decorative pieces, including elements of the Studio House for the designer Jacques Doucet.After 1928, Csaky moved away from Cubism into a more figurative or representational style for nearly thirty years. He exhibited internationally across Europe, but some of his pioneering artistic innovation was forgotten. His work today is primarily held by French and Hungarian institutions, as well as galleries and private collections both in France and abroad.
