Paul Klee. Catalogue raisonné: Band 1, 1883–1912

Paul Klee’s was a Swiss born painter, with a unique style that was influenced by expressionism, cubism, surrealism, and orientalism. Klee remained isolated from the developments of modern art until 1911, when he met Wassily Kandinsky, Franz Marc, and August Macke of Der Blaue Reiter. He participated in the second Blaue Reiter exhibition in 1912 and saw there the work of other avant‑garde artists such as Robert Delaunay, Pablo Picasso, and Georges Braque. Klee visited Delaunay's studio in Paris that same year. His experiments with abstraction began at about this time.
