Dieter Wisliceny (13 January 1911 – 4 May 1948) was a member of the Schutzstaffel (SS), and a key executioner in the final phase of the Holocaust.
Joining the Nazi Party in 1933 and enlisting in the SS in 1934, Wisliceny eventually rose to the rank of SS-Hauptsturmführer (captain) in 1940; he worked in the Reich Security Head Office Referat IV B4 under Adolf Eichmann. During implementation of the Final Solution, his task was the ghettoization and liquidation of several important Jewish communities in Nazi-occupied Europe, including those of Greece, Hungary and Slovakia. Wisliceny also re-introduced the yellow star in occupied countries; the yellow star being used to distinguish Jews from non-Jews. He was involved in the deportation of the Hungarian Jews in 1944.
Wisliceny was an important witness at the Nuremberg trials. His testimony would later prove important in the successful prosecution of Eichmann for his complitcy in the Holocaust in Israel in 1961.
Wisliceny was extradited to Czechoslovakia, where he was tried and hanged for war crimes in 1948.
Dieter Wisliceny in his testimony given before the International Military Tribunal at Nuremberg, 3 January 1946, erroneously identifies the Auschwitz concentration camp as the concentration area Sosnowitz (which was one of its dozens of subcamps)
