A.F. van Ravesteijn (1922) was working at a printing press in The Hague, when he was sent to Germany for the ‘Arbeitseinsatz’ in 1942. He ended up in Recklinghausen and is forced to work in the administration of a labour camp. After his liberation, the Brits ask him to stay on, because he had come to know a lot about German mining in the Ruhr-area. In the late 40’s, Van Ravesteijn returned to the Netherlands, where he became a German teacher.
