Paul Klee (18 December 1879 – 29 June 1940) 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, as well, a student of orientalism. Klee was a natural draftsman who experimented with and eventually mastered color theory, and wrote extensively about it. His works reflect his dry humor and his sometimes child-like perspective, his personal moods and beliefs, and his musicality.
Klee has been variously associated with Expressionism, Cubism, Futurism, Surrealism, and Abstraction, but his pictures are difficult to classify. He generally worked in isolation from his peers, and interpreted new art trends in his own way. He was inventive in his methods and technique. Klee worked in many different media—oil paint, watercolor, ink, pastel, etching, and others. He often combined them into one work. He used canvas, burlap, muslin, linen, gauze, cardboard, metal foils, fabric, wallpaper, and newsprint.
