Kaspar Hauser, German feral child (born 1812?)

Kaspar Hauser was a German youth who claimed to have grown up in the total isolation of a darkened cell. His claims, and his subsequent death from a stab wound, sparked much debate and controversy both in Nuremberg and abroad. Theories propounded at the time identified Hauser as a member of the grand ducal House of Baden, hidden away because of dynastic intrigue. However, there were also allegations that Hauser was an impostor. In 2024, a scientific study ruled out Hauser's princely descent by comparing mitochondrial DNA haplotypes with the House of Baden.

A feral child is a young individual who has lived isolated from human contact from a very young age, with little or no experience of human care, social behavior, or language. Such children lack the basics of primary and secondary socialization. The term is used to refer to children who have suffered severe abuse or trauma before being abandoned or running away. They are sometimes the subjects of folklore and legends, often portrayed as having been raised by animals. While there are many cases of children being found in proximity to wild animals, there are no eyewitness accounts of animals feeding human children.
