Hermann Hahn war Jugendführer des Betar St. Pölten und aktiver Zionist. Er wanderte bereits 1933 nach Palästina aus und war besonders stolz, dass allen Mitglieder seiner Betar-Gruppe die rechtzeitige Ausreise gelang. Weil er illegal nach Palästina eingereist war, konnte er seine Eltern nicht nachholen.
Hermann Hahn was the youth leader of the Betar St. Pölten and an active Zionist. He emigrated to Palestine as early as 1933 and was particularly proud that all members of his Betar group managed to emigrate in time. Because he had entered Palestine illegally, he was unable to get his parents to his new home country as well.
