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 and proposed his birth had been hidden as part of royal intrigue. These opinions have long since been rejected by historians,1 and many argued during and after Hauser's life that he was most likely a fraud.
