Wassily Wassilyevich Kandinsky (16 December 1866 - 13 December 1944) was a Russian painter, printmaker and art theorist. One of the most famous 20th-century artists, he is credited with painting the first modern abstract works. In 1896 he settled in Munich and studied first in the private school of Anton Abe and then at the Academy of Fine Arts, Munich. He went back to Moscow in 1914 after World War I started. He was unsympathetic to the official theories on art in Moscow and returned to Germany in 1921. There he taught at the Bauhaus school of art and architecture from 1922 until the Nazis closed it in 1933. He then moved to France where he lived the rest of his life, and became a French citizen in 1939.
