After the German invasion of the Netherlands of May 1940, in early 1941, the German occupiers forced Dutch Universities to exclude Jewish staff and students. However, Eddy, who was studying medicine at the University of Leiden, was able, with the help of his professors, to accelerate his studies. He was, in fact, the last Jewish medical student to receive a degree from the University of Leiden. Eddy reported to the camp after his mother was arrested and taken to Westerbork. The Jewish council promised him that if he volunteered to register as a doctor for the transit camp, his mother would be released. However, when De Wind arrived at Westerbork, it turned out that his mother had already been taken to Auschwitz. Nevertheless, Eddy stayed at Westerbork, where he met his first wife, a nurse at the camp, Friedel Komornikand even married. In the end Eddy and his new wife were both deported to Auschwitz.
