The Stolpersteine (stumbling stones) project is the initiative of artist Gunter Demnig, meant to commemorate those persecuted by the Nazis between 1933 and 1945. The blocks have the names and fate of the person they commemorate engraved into a brass plate on the top of each Stolperstein, and are laid into the pavement in front of the last voluntarily places of residence of the victims of the Nazis. The specific block of Mrs. Metz was an initiative of Tal Alon and Olaf Kühnemann who live down the street from the house of which she was deported to Theresienstadt Ghetto, where she died.
