Simon Wiesenthal, Austrian human rights activist, Holocaust survivor (born 1908)

Simon Wiesenthal was an 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, the Kraków-Płaszów concentration camp, the Gross-Rosen concentration camp, a death march to Chemnitz, Buchenwald, and the Mauthausen concentration camp.

The Holocaust, known in Hebrew as the Shoah, was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. Separate Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups.
