Since 2014 Yitzak Rabbin Highschool in Israel and Karl-Theodor-v.-Dalberg-Gymnasium in Germany have been working together for a common goal: To convey the personal histories of Holocaust victims to the public. In order to commemorate the victims of the Holocaust, the students research and write the biographies of Jewish citizens of Aschaffenburg, who were murdered in the Holocaust. Those biographies can be viewed with this app. By working in archives the German students collect information about the “persons behind the stumbling blocks“ that are installed in Aschaffenburg. The biographies are then translated by Israelis students into Hebrew. The texts are available in German, English and Hebrew.
