Paul Klee, born in 1879 in Münchenbuchsee, Switzerland, was one of the most important artists of Classical Modernism. Klee started his career as a printmaker and exhibited his prints with the artist group Der Blaue Reiter. In 1914, he went on a trip to Tunisia with August Macke and Louis Moilliet, which led to a breakthrough for him: he not only dared to work with graphics, but began to paint first with watercolour, then eventually with oil. Klee combined translucent color surfaces and cubist perspectives with a childlike and playful style. Paul Klee taught at the Bauhaus in Weimar and in Dessau. Later he taught at the Düsseldorf Art Academy until he was dismissed by the Nazi regime in 1933.
