The National Socialist military building authority was in charge of the 1937 construction of the “Invalidensiedlung,” a housing estate built for disabled veterans of World War I. It consisted of fifty two-story clinker-brick houses with 150 apartments with wheelchair access, along with outbuildings and a community building. A memorial plaque and the street Staehleweg recall the estate’s commander, Colonel Wilhelm Staehle. Staehle had helped people being persecuted by the Nazi regime and had also helped to plan the attempt to kill Hitler. He was arrested even before the attempt took place on 20 July 1944 and was shot by the SS in April 1945.
