Paul Klee (18 December 1879 Bern, Switzerland – 29 June 1940 Ticino, Switzerland) was a painter and graphic artist.
His work is attributed to Expressionism, Constructivism, Cubism, Primitivism and Surrealism. Klee associated himself with the group Der Blaue Reiter (The Blue Rider).
Like his friend, the painter Wassily Kandinsky, Klee taught at the Bauhaus in Weimar from 1920 and later in Dessau. From 1931 he was a professor at the Kunstakademie Düsseldorf. He was dismissed after the seizure of power by the National Socialists and went back to Bern, where, during the last years from 1934 onwards, in spite of his severe illness, an extensive late work arose. In addition to his artistic work he wrote art theorical writings. Paul Klee is one of the most important visual artists of the 20th century.
