Simon Wiesenthal (31 December 1908 – 20 September 2005) was a Jewish Austrian Holocaust survivor, Nazi hunter, and writer. He studied architecture and was living in Lwów at the outbreak of World War II. He survived the Janowska concentration camp (late 1941 to September 1944), the Kraków-Plaszów concentration camp (September to October 1944), the Gross-Rosen concentration camp, a death march to Chemnitz, Buchenwald, and the Mauthausen-Gusen concentration camp (February to 5 May 1945). After the war, Wiesenthal dedicated most of his life to tracking down and gathering information on fugitive Nazi war criminals so that they could be brought to trial. In 1947 he co-founded the Jewish Historical Documentation Centre in Linz, Austria, where he and others gathered information for future war crime trials and aided refugees in their search for lost relatives. He opened the Documentation Centre of the Association of Jewish Victims of the Nazi Regime in Vienna in 1961 and continued to try to locate missing Nazi war criminals. He played a small role in locating Adolf Eichmann, who was captured in Buenos Aires in 1960, and worked closely with the Austrian justice ministry to prepare a dossier on Franz Stangl, who was sentenced to life imprisonment in 1971.
