Jens Bjørneboe (1920–1976), once called “the greatest failed novelist of the twentieth century,” was a Norwegian novelist, playwright, and anarcho-nihilist. Jens wrote honestly and angrily, a trait that found him convicted of obscenity and resulted in his novel Without A Stitch being banned in Norway for a time. Perhaps his strongest allegorical work is his last novel, The Sharks. He also wrote anarchist theory, expounding on the idea that anarchism was scientific (contrasting with the dogmatic Marxism) and existed in varying degrees. After a lifetime of controversy and alcohol, he took his own life.
