Otto Hahn

Otto Hahn (1879–1968) was a German chemist who received the 1944 Nobel Prize in Chemistry for discovering nuclear fission. He is considered a pioneer of radioactivity and radiochemistry. He did not work on Germany's atomic bomb project during World War II, but he was detained with nine other scientists by the Allied Forces. After the war, Hahn reentered academia and research.

Otto Hahn (1879-1947) was one of several scientists captured by the German Freedom Front in 1946. It had been Reinhard Heydrich's hope that the scientists might build the GFF an atomic bomb. Karl Wirtz disabused Heydrich of that notion.

Nonetheless, Hahn and his fellows were held in the underground Alpine Redoubt until 1947. When American forces arrived, Heydrich escaped, and ordered Hahn and several other scientists killed.
