The German Reichsbahn operated a forced labour camp in what is now the Rudolf Wissell school. Because of bomb attacks, the children had been evacuated to the countryside. Many schools in Berlin were used as forced labour camps.

In the camp in Ellerbeker street, the Reichsbahn housed entire families. Józef Przedpełski and his pregnant wife arrived to the classrooms that had been set up as dormitories in September, 1944.

Their son was born here shortly before the end of the war.
