“Stumbling stone”-memorial for Karl and Charlotte Schneider, last living in St. Johann im Pongau, Wagrainerstraße 6, Land Salzburg, Austria,victims of the Holocaust. Stolperstein is the German word for "stumbling block", "obstacle", or "something in the way". The artist Gunter Demnig has given this word a new meaning, that of a small, cobblestone-sized memorial for a single victim of Nazism set in the pavement before the building in which this person lived or worked. The placement of these two stumbling blocks was initiated by the Association History Workshop St. Johann im Pongau.
