Erich Mühsam (6 April 1878 – 10 July 1934) was a German antimilitarist anarchist essayist, poet and playwright. He emerged at the end of World War I as one of the leading agitators for a federated Bavarian Soviet Republic, for which he served 5 years in prison. Also a cabaret performer, he achieved international prominence during the years of the Weimar Republic for works which, before Adolf Hitler came to power in 1933, condemned Nazism and satirized the future dictator. Mühsam was tortured and murdered in the Oranienburg concentration camp in 1934. Source: Wikipedia (en)
