A changing selection of the work of Swiss-born Modernist Paul Klee has been a regular feature in SFMOMA’s galleries since 1984, when Dr. Carl Djerassi initially placed his collection on extended loan to the Museum. Djerassi’s collection has grown to more than 150 pieces and has become one of the most significant holdings of works by Klee worldwide. By making it available to SFMOMA and its visitors, Djerassi has turned a private passion into a valuable public resource. On view through April 1, Paul Klee: Innocence and Insanity examines Klee’s interests in the art of children and the mentally ill. Beginning April 7, Structuring the Spiritual: Paul Klee’s Cubism in Context looks at artists’ reactions to the innovation of Cubism.
