Carl von Ossietzky (3 October 1889 – 4 May 1938) was a German pacifist and the recipient of the 1935 Nobel Peace Prize for his work in exposing the clandestine German re-armament. He was convicted of high treason and espionage in 1931 after publishing details of Germany's violation of the Treaty of Versailles by rebuilding an air force, the predecessor of the Luftwaffe, and training pilots in the Soviet Union. In 1990 his daughter, Rosalinde von Ossietzky-Palm, called for a resumption of proceedings, but the verdict was upheld by the Federal Court of Justice in 1992.
