Gunter Demnig

Gunter Demnig (German pronunciation: [ˈɡʊntɐ ˈdɛmnɪç]; born 27 October 1947) is a German artist. He is best known for his Stolperstein ("stumbling block") memorials to the victims of Nazi persecution, including Jews, homosexuals, Romani and the disabled. The project places engraved brass stones in front of a former residence for a Holocaust victim who was deported and murdered by Nazi Germany. The memorial effort began in Germany and has since spread, with more than 100,000 stones placed across 26 countries in Europe.
