Paul Klee was a Swiss painter of German nationality. His highly individual style was influenced by movements in art that included expressionism, cubism, and surrealism. He was also a student of orientalism. Klee was a natural draftsman who experimented with and eventually mastered color theory, after which he wrote about extensively. His works reflect his dry humor and sometimes child-like perspective, his personal moods and beliefs and his musicality. He and his friend, Russian painter Vasily Kandinsky, both taught at the German Bauhaus school of art and architecture.
