3,900 Pages of Paul Klee’s personal notebooks (1921-1931) are online. I love his art and thoughts on color and really enjoy his works. Klee taught at the Bauhaus in Weimar from 1921 to 1926 and in Dessau from 1926 to 1931. During his tenure, he was in close contact with other Bauhaus masters such as Kandinsky and Lyonel Feininger.
