World Disarmament Conference
Carl von Ossietzky exposed the reality of the German rearmament in 1931 and his disclosures won him the 1935 Nobel Peace Prize but he was imprisoned and tortured by the Nazis, dying of tuberculosis in 1938. Von Ossietzky's disclosures also triggered the re-armament policy in Great Britain, which escalated after Adolf Hitler withdrew Germany from the League of Nations and the World Disarmament Conference in 1933.
