Simon Wiesenthal was born in
Buczacz, then part of Austria-Hungary (present-day Ukraine), and studied architectural engineering at the Technical University of Prague and in Lviv. In 1936, he married Cyla Müller. After the Nazi invasion of Lviv in World War II in 1941, Wiesenthal was separated from his wife and sent to forced labor and to five German concentration camps, including Buchenwald and Mauthausen. He and his wife, who also managed to survive, were reunited at the end of the war. He founded and led the Jewish Documentation Centre in Vienna and dedicated his life to the search for and legal prosecution of Nazi war criminals and to promoting Holocaust memory and education. His best-known published work was his memoir, The Murderers Among Us (1967).
