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 in North America and worldwide. By making it available to SFMOMA and its visitors, Djerassi — himself a chemist, novelist, and playwright — has turned a private passion into an infinitely valuable public resource. This selection of 23 works on paper, part of an ongoing presentation within Matisse and Beyond, features works amassed by Djerassi since 2000. Opening October 14, Paul Klee: Innocence and Insanity examines Klee's interests in the art of both children and the mentally ill.
