Kaspar Hauser (born April 30, 1812—died December 17, 1833, Ansbach) was a German youth around whom gathered one of the 19th century's most-celebrated mysteries.
On May 26, 1828, Hauser was brought before the authorities in Nuremberg, apparently bewildered and incoherent. With him he had a letter purporting to have been written by a labourer, into whose custody, it stated, the boy had been delivered on October 7, 1812, with the proviso that he should be instructed in reading, writing, and the Christian Religion but kept in close confinement. Enclosed with this letter was one purporting to have been written by the boy's mother, giving his name and his date of birth and stating that his father was a deceased cavalry officer. At first detained as a vagrant, the boy was later taken under the care of the educationist Georg Daumer. Next, the 4th earl of Stanhope took the boy under his protection (1832) and sent him to Ansbach, where he became a clerk in the office of the president of the court of appeal, Anselm von Feuerbach. The youth died from a wound that was either self-inflicted or, as he claimed, dealt by a stranger.
