The opening up of Stasi archives after 1990 provided access to large amounts of information about the National Socialist years that had hitherto not been available to researchers and the wider public. Documents that had survived the war concerning Kallenbach's imprisonment and trial had been carefully archived and put away by the East German authorities, presumably while the region was still being administered as the Soviet occupation zone. A Berlin street was named after Kallenbach in 2006. Since then she has become a named victim of the Hitler government, invoked to represent thousands of others whose names remain lost to history.
