On 26 May 1828, a teenage boy appeared in the streets of Nuremberg, Germany. The boy, who answered to the name Kaspar Hauser, claimed to have grown up in the total isolation of a darkened cell. Hauser's claims, and his subsequent death by stabbing, sparked much debate and controversy. Some theories about him at the time linked him with the grand ducal House of Baden to be the hereditary "Prince of Baden".
