About Mavro Frankfurter, Rabbi
Mavro Frankfurter was the rabbi of the Yugoslav town of Vinkovci.
His son David had shot Wilhelm Gustloff in Switzerland in 1936. Then, Mavros had condemned his son's action.
In 1941, as the German soldiers occupied the town, Rabbi Frankfurter was made to stand on a table while the soldiers spat in his face, pulled out the hair from his long beard, and struck him with their rifle butts.
