Ossietzky, Carl von (fən ôsyĕtˈskē) [key], 1889–1938, German pacifist. A leader of the peace movement in Germany after World War I, he was editor of the antimilitarist weekly Weltbühne from 1927. Ossietzky was imprisoned (1932) for articles exposing secret rearmament in Germany. After Adolf Hitler's rise to power in 1933, Ossietzky was sent to a concentration camp. Suffering from tuberculosis, he was removed (1936) to a prison hospital shortly before the announcement that he had been awarded the 1935 Nobel Peace Prize. The German government protested and barred all Germans from future acceptance of a Nobel Prize. Still imprisoned, Ossietzky died two years later. His collected writings were published in an eight-volume German edition in 1995.
