Background: Paul Klee (German: [paUl 'kle:]; 18 December 1879 - 29 June 1940) was a Swiss German artist. His highly individual style was influenced by movements in art that included Expressionism, Cubism, and Surrealism. Klee was a natural draftsman who experimented with and eventually deeply explored color theory, writing about it extensively; his lectures Writings on Form and Design Theory (Schriften zur Form und Gestaltungslehre), published in English as the Paul Klee Notebooks, are held to be as important for modern art as Leonardo da Vinci's A Treatise on Painting for the Renaissance. He and his colleague, Russian painter Wassily Kandinsky, both taught at the Bauhaus school of art, design and architecture.

Conteúdo: In 1919, Klee applied for a teaching post at the Academy of Art in Stuttgart. This attempt failed but he had a major success in securing a three-year contract (with a minimum annual income) with dealer Hans Goltz, whose influential gallery gave Klee major exposure, and some commercial success. A retrospective of over 300 works in 1920 was also notable.  Klee taught at the Bauhaus from January 1921 to April 1931. He was a "Form" master in the bookbinding, stained glass, and mural painting workshops and was provided with two studios. In 1922, Kandinsky joined the staff and resumed his friendship with Klee. Later that year the first Bauhaus exhibition and festival was held, for which Klee created several of the advertising materials. Klee welcomed that there were many conflicting theories and opinions within the Bauhaus: "I also approve of these forces competing one with the other if the result is achievement."  Klee was also a member of Die Blaue Vier (The Blue Four), with Kandinsky, Lyonel Feininger, and Alexej von Jawlensky; formed in 1923, they lectured and exhibited together in the USA in 1925. That same year, Klee had his first exhibits in Paris, and he became a hit with the French Surrealists. Klee visited Egypt in 1928, which impressed him less than Tunisia. In 1929, the first major monograph on Klee's work was published, written by Will Grohmann.  Klee also taught at the Dusseldorf Academy from 1931 to 1933, and was singled out by a Nazi newspaper, "Then that great fell
