I'm Not Stiller by Max Frisch
Max Rudolf Frisch (May 15, 1911 – April 4, 1991) was a Swiss architect, playwright and novelist, regarded as highly representative of German literature after World War II. In his creative works Frisch paid particular attention to issues relating to problems of human identity, individuality, responsibility, morality and political commitment. His use of irony is a significant feature of his post-war publications. Frisch was a member of the Gruppe Olten.
