Wiesenthal spent time at his office at the Documentation Centre of the Association of Jewish Victims of the Nazi Regime in Vienna even as he approached his 90th birthday. He finally retired in October 2001, when he was 92. The last Nazi he had a hand in bringing to trial was "Untersturmführer" Julius Viel, who was convicted in 2001 of shooting seven Jewish prisoners. "I have survived them all. If there were any left, they'd be too old and weak to stand trial today. My work is done," said Wiesenthal. Cyla died on 10 November 2003, at age 95, and Wiesenthal died on 20 September 2005, age 96. He was buried in Herzliya, Israel.
