Baum und Architektur-Rhythmen (Tree and Architecture-Rhythms) - Paul Klee 1920

Klee was born in 1879 in Münchenbuchsee, near Bern, Switzerland, the second child of Hans Klee, a German music teacher, and a Swiss mother. His training as a painter began in 1898 when he studied drawing and painting in Munich for three years. By 1911, he had returned to that city, where he became involved with the German Expressionist group Der Blaue Reiter (The Blue Rider), founded by Vasily Kandinsky and Franz Marc in 1911. Klee and Kandinsky became lifelong friends, and the support of the older painter provided much-needed encouragement. Until then, Klee had worked in relative isolation, experimenting with various styles and media, such as making caricatures and Symbolist drawings, and later producing small works on paper mainly in black and white. His work was also influenced by the Cubism of Pablo Picasso and Georges Braque, and the abstract translucent color planes of Robert Delaunay.
