Kaspar Hauser

About 5 min read

On 26 May 1828, a teenage boy was found wandering the streets of Nuremberg, then part of the Kingdom of Bavaria. He wore rough country clothing, moved awkwardly, and seemed able to say very little. In his possession were two letters. One said he had been kept in close confinement since infancy. The other said his name was Kaspar, that he had been born on 30 April 1812, and that his father, a cavalryman, was dead. He could write his own name: Kaspar Hauser. Within weeks he was famous across Europe. Within five years he was dead from a stab wound, and the argument about who he was had only just begun.

The Boy Who Appeared in Nuremberg

Hauser was found on Whit Monday, 26 May 1828, near the Unschlittplatz. A shoemaker named Weickmann brought him to Captain Friedrich von Wessenig, commander of the 4th squadron of the 6th cavalry regiment, to whom one letter was addressed. The first letter, purporting to come from the poor labourer who had looked after the boy, said the writer had taken custody of Hauser as an infant on 7 October 1812, had taught him reading, writing and the Christian religion, but had never let him leave his confinement. Now, it said, the boy wished to become a cavalryman like his father, and the writer was releasing him to that life.

The second letter was presented as having been written by Hauser’s mother. It gave the boy’s name as Kaspar, his birth date as 30 April 1812, and said his father had been a cavalryman of the 6th regiment and was dead. At first Hauser reportedly repeated only a few phrases, among them that he wanted to be a cavalryman, as his father had been. He is said to have disliked most food except bread and water. The authorities treated him as a vagrant, holding him for about two months in the Luginsland Tower in Nuremberg Castle, in the care of the jailer Andreas Hiltel.

The Story of the Dark Cell

The town authorities entrusted Hauser on 18 July 1828 to the schoolmaster Georg Friedrich Daumer, who became his guardian. Under Daumer, Hauser learned quickly and began to give an account of his childhood that became the core of the mystery. He said he had lived for as long as he could remember in a small, darkened cell, visited only by a masked man who brought bread and water, and had never seen another human face or been outside. Only shortly before his appearance in Nuremberg, he said, had the man taught him to walk and to write his name, and then brought him to the city.

Paul Johann Anselm Ritter von Feuerbach, president of the Bavarian court of appeals, investigated the case and became convinced Hauser was telling the truth in essentials. His 1832 book spread the story widely. Others were less sure. Some observers noted that Hauser learned suspiciously fast, that his account grew more detailed as he learned what his listeners wanted to hear, and that parts of it changed over time. The letters were unsigned in any verifiable way, and their authors were never identified. Everything about Hauser’s early life comes, directly or indirectly, from Hauser himself.

Attacks, Patrons and a Violent Death

On 17 October 1829 Hauser was found in the cellar of Daumer’s house, bleeding from a wound to his forehead. He said a hooded man had attacked him, and that he recognised the voice as that of the man who had brought him to Nuremberg. The blood trail suggested a confused sequence of movements through the house, and not everyone accepted his account.

The English nobleman Lord Stanhope became interested in Hauser, paid for his upkeep, and in 1832 sent him to Ansbach to be educated under a Dr Meyer. Hauser later worked as a clerk in Feuerbach’s office. Stanhope, at first sympathetic, eventually became openly sceptical of Hauser’s stories.

On 14 December 1833, Hauser came home in Ansbach clutching a deep wound in his left breast. He said a stranger had lured him to the court garden and stabbed him there. He died on 17 December 1833, aged 21 by the dates in the letters. His tombstone in Ansbach is reported to carry the words: “Here lies Kaspar Hauser, an enigma of his time. His birth is unknown, his death a mystery.” Some contemporaries believed he had inflicted the wound himself, intending a shallow cut that would revive interest in his story, and that it went deeper than he meant. Others believed an assassin had caught up with him. No attacker was ever identified.

The Prince Theory — and What DNA Did to It

The most famous explanation was dynastic: Hauser was the hereditary prince of Baden, son of Grand Duke Karl of Baden and Stéphanie de Beauharnais, swapped as a baby and hidden away so a collateral branch of the family could take the throne. Feuerbach himself leaned towards a version of this idea. It survived for nearly two centuries. It did not survive modern genetics.

A 1998 analysis of a bloodstain from underwear said to have been Hauser’s found no maternal match with the Baden family, but later tests produced conflicting results and the authenticity of some samples was disputed. In September 2024, a team led by Walther Parson of the Medical University of Innsbruck published a new study in the journal iScience. Using modern massively parallel sequencing on several hair samples attributed to Hauser, together with the earlier blood sample, researchers in three independent laboratories obtained the same mitochondrial DNA type from the Hauser samples. That type was clearly different from the mitochondrial lineage of the House of Baden. The prince theory was ruled out.

That is a precise result, and its limits matter. Mitochondrial DNA is passed down the maternal line, so the study rules out that particular maternal descent. It does not reveal who Hauser’s parents actually were, where he was born, or whether his account of confinement was true. As co-author Turi King noted, the data still could not say who he was. Parson added that a negative result should not be read as proof of fraud: Hauser might still have been a crime victim, even if he was not a prince.

What Remains Unknown

We know a young man calling himself Kaspar Hauser appeared in Nuremberg on 26 May 1828, became a public figure, suffered unexplained injuries, and died of a stab wound in Ansbach in December 1833. We know the prince theory is genetically excluded. We do not know his real parents, his birthplace, or his childhood. We do not know whether he spent years in a dark cell, whether he invented or exaggerated that account, or whether the attacks on him — including the fatal one — were staged, self-inflicted or carried out by someone else. The letters have never been traced to a writer, and the masked man has never been identified. Hauser is a mystery of evidence as much as of identity: a case in which the central witness was also the central suspect.

What Is Documented, and What Is Not

Documented: Hauser appeared in Nuremberg on 26 May 1828 carrying two letters; he was taken in by Daumer on 18 July 1828; he was wounded in the forehead on 17 October 1829; he died in Ansbach on 17 December 1833 from a stab wound received on 14 December 1833; the 2024 iScience study found that mitochondrial DNA from samples attributed to Hauser does not match the House of Baden maternal lineage, ruling out the prince theory.

Unverified or disputed: That Hauser spent his childhood in total isolation in a dark cell; the authorship and truth of the two letters; the identity of the masked man; whether the 1829 attack or the fatal 1833 stabbing was inflicted by another person or by Hauser himself; Hauser’s true parentage and birthplace.
