One of the most helpful supporters of my research was Dr. Karola Fings from the NS-Documentation Center Köln.
Furthermore we visited the Memorial site Rosbach on Sieg and got information from the Memorial site Düsseldorf as well as from the Memorial site Dachau. A helpful project also was the Memorial book for the NS-victims of Wuppertal.
