Since 1947, Wiesenthal continued this work independently in Linz. There, he founded a centre for jüdische historische Dokumentation (Jewish Historical Documentation). In 1961, he moved to Vienna, where he opened the Dokumentationszentrum des Bundes Jüdischer Verfolgter des Naziregimes (Documentation Centre of the Associaton of Jewish Victims of the Nazi Regime). Wiesenthal tirelessly collected evidence and testimonies. Although the Austrian authorities hardly supported him, Wiesenthal was successful in bringing numerous perpetrators to trial, including: Adolf Eichmann, Franz Stangl (commandant of Treblinka extermination camp) and Franz Murer (“the butcher of Vilnius”).
