Friedrich Dürrenmatt was a Swiss author and dramatist. He was a proponent of epic theatre whose plays reflected the recent experiences of World War II. The politically active author's work included avant-garde dramas, philosophical crime novels, and macabre satire. Dürrenmatt was a member of the Gruppe Olten, a group of left-wing Swiss writers who convened regularly at a restaurant in the city of Olten.
