Paul Klee Ernst (* Dec. 18, 1879 - † June 29, 1940) is one of the most important visual artists of classical modernism of the 20th century. His versatile work makes part of Expressionism, Cubism and Surrealism altogether. He also was closely related to the "Blue Rider" artistic group.
Klee traveled in 1914 with August Macke and Louis Moilliet to Tunis, where he met Ferdinand Hodler. In 1920, Klee and his friend, painter Wassily Kandinsky, became teachers at Weimar and Dessau Bauhaus. In 1931, he became a professor at the Dusseldorf Art Academy.
After the Nazi takeover, he returned to Bern, where he spent his last years fighting against a long illness.
