Klee was born near Berne, Switzerland and studied art in Munich. In 1912, his work was included in the second exhibition of the 'Blaue Reiter' (Blue Rider) Expressionist group. In the same year, he saw an exhibition of cubist paintings in Paris, which had a great influence on his style. Klee spent ten years as a teacher at the Bauhaus from 1921, along with Kandinsky. He was dismissed from a teaching post at the Düsseldorf Academy in 1933 by the Nazis and his work was included in the Degenerate 'Art' exhibition. A highly inventive and prolific artist, Klee produced around nine thousand pieces in his lifetime, usually working on a small scale.
