Investment manager Aryeh Rubin and Efraim Zuroff, head of the Simon Wiesenthal Center's Israeli operation, will announce the offer at the German Bundestag in Berlin Jan. 26.
It will be called "Operation: Last Chance."
A similar offer was issued in 2002 in the Baltic states and Eastern Europe. Rewards of $10,000 were offered for tips leading to prosecution and conviction of war criminals.
So far, the offer has generated 326 tips in places such as Croatia, Romania, Lithuania, Latvia, Estonia, Ukraine, Poland and Austria.
Those who called have named people and identified burial sites and towns where atrocities occurred.
Rubin's Targum Shlishi foundation has paid $5,000 so far, half a reward to a Croation man whose tip led to a 90-year-old Nazi collaborator.
But 72 names have been provided to prosecutors in Ukraine, Latvia and Lithuania. Eighteen murder investigations have been opened in Latvia and Lithuania.
