This source is a short article of fifty-four lines that was published in the newsletter of Hamburg's Jewish congregation on the occasion of the Joseph Carlebach School's reopening in the fall of 2007. Its author is the journalist and writer Daniel Killy, who also was the Jewish congregation's spokesperson at the time.

In the article, Killy reports about the opening of the Joseph Carlebach School located at Grindelhof 30, which opened its doors to 18 children attending preschool and first grade on August 28, 2007. He describes the daily routine and the concept of “rhythmicization,” meaning the multi-methodical composition of the school day at this all-day school, which follows the ideas of pedagogue Joseph Carlebach, for whom the school is named. In addition to principal Heinz Hibbeler, Killy quotes rabbi Shlomo Bistritzky, who highlights the significance of this new school for the rebuilding of Jewish life in Hamburg.
