Years spent together at a boarding school forged bonds. Even if school and apprenticeship left little leisure time, many "Ahlemers" mention close personal relationships and the diversity of cultural and sporting activities in their memoirs. Following the Nazis rise to power in 1933, the school grounds became a temporary place of refuge for children and young people offering them protection. The alumni "Association of Former Ahlemers" was responsible for the flow of information between the school and its graduates. Often ‘Ahlemers’ maintained far-reaching contacts, thus creating a worldwide alumni network.
