Harold Grunwald † (brother)
Robert Grunwald was a German Shadowhunter who lived during the 18th century.
In 1721 Robert and his brother Harold set fire to a local tavern in which the entire local werewolf pack was gathered. This horrified the Clave and resulted in a trial which led to the brothers being handed over to mundane authorities, who hanged them. The werewolf hunts died away completely after this.
