Carl von Ossietzky, German journalist and activist, Nobel Prize laureate (b. 1889)
Carl von Ossietzky (German: [ˈkaʁl fɔn ʔɔˈsi̯ɛtskiː] (listen); 3 October 1889 – 4 May 1938) was a German journalist and pacifist. He was the recipient of the 1935 Nobel Peace Prize for his work in exposing the clandestine German re-armament.As editor-in-chief of the magazine Die Weltbühne, Ossietzky published a series of exposés in the late 1920s, detailing 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. He was convicted of treason and espionage in 1931 and sentenced to eighteen months in prison but was granted amnesty in December 1932.

Ossietzky continued to be a vocal critic against German militarism after the Nazis' rise to power. Following the 1933 Reichstag fire, Ossietzky was again arrested and sent to the Esterwegen concentration camp near Oldenburg. In 1936, he was awarded the 1935 Nobel Peace Prize but was forbidden from travelling to Norway and accepting the prize. After enduring years of mistreatment and torture in various Nazi concentration camps, Ossietzky died of tuberculosis in 1938 in a Berlin hospital.
