Simon Wiesenthal in 2000
21 September 2005 -- Dignitaries from around the world are expected to attend a memorial service today in Vienna for Simon Wiesenthal, the Nazi war crimes investigator.
The 96-year-old Holocaust survivor died yesterday in his sleep in the Austrian capital.
Tributes continue to pour in for Wiesenthal.
U.S. President George W. Bush called him "a tireless and passionate advocate" who devoted his life to tracking down Nazi killers and promoting freedom.
German Chancellor Gerhard Schroeder said Wiesenthal was "dedicated to justice in trying to give back the victims of the Holocaust their visage and dignity."
UN Secretary-General Kofi Annan said Wiesenthal's efforts had helped the UN's own attempts to promote tolerance and fight anti-Semitism.
Wiesenthal will be buried in Israel on 23 September.
