Kaspar Hauser
Kaspar Hauser (30 April 1812 (?) – 17 December 1833) was a German youth who 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. Theories propounded at the time linked him with the grand ducal House of Baden. These have long since been rejected by historians.
