Peter: The Wild Boy Who Became A “Human Pet”

Discovered naked and alone in the German wilderness in 1725, “Peter the Wild Boy” was about 11 years old when he was rescued. It’s believed that he was abandoned by his parents, who likely couldn’t afford to raise him.

After he was discovered, everyone called him Peter, but no one knew if that was actually his real name. Like many feral people left to fend for themselves, Peter was unable to talk. He also hated wearing clothes.

The following year, when Peter was about 12, he was transported to London, where he would become the “human pet” of King George I. There, the “wild boy” ran around on all fours and picked the pockets of courtiers at Kensington Palace. Sometimes, he also “stole kisses” from them.

It was widely believed that Peter had been raised by wolves or bears, as his behavior made it clear that he had not spent much time with people. The Age of Enlightenment made Peter’s condition all the more fascinating to English high society, as they questioned what it meant to be human.

Meanwhile, many in the palace grew tired of Peter’s antics, especially his poor table manners and his insistence on sleeping on the floor. Eventually, the court paid for Peter’s retirement at a farm in Hertfordshire.

He spent the rest of his life surrounded by kind farmers but was forced to wear a collar that read: “Peter the Wild Man of Hanover. Whoever will bring him to Mr. Fenn at Berhamsted shall be paid for their trouble.”

Peter died in 1785 and was buried in the cemetery of St. Mary’s at Northchurch. Since then, experts have used Peter’s portraits to hypothesize that he had suffered from Pitt-Hopkins Syndrome — a rare genetic condition that causes distinctive facial features as well as an intellectual disability. Tragically, that may explain why his parents abandoned him.

Kaspar Hauser: The Mysterious Teenager Who Wandered Into Nuremberg

On May 26, 1828, residents of Nuremberg, Germany, encountered a 16-year-old boy in bedraggled clothing passing through a public square. The mysterious teenager appeared to be unable to read, write, or recall anything about his life except for that his name was Kaspar Hauser.

Hauser carried two letters in an envelope that initially seemed to clarify a few things. The first letter addressed the captain of a local calvary and asked him to place the boy in his regiment. The second was dated 1812 and was supposedly written by the boy’s mother. It explained that the boy’s father had died, and reiterated that Hauser must join the military.

When authorities took Hauser into custody, they found him repulsed by all food and drink save for bread and water. Strangely, he also walked as though he had only just learned how to. And in the rare instances that he spoke, he mainly mumbled about horses. Made a ward of the city, Hauser was eventually put in custody of a British nobleman named Lord Stanhope.

Incredibly, just weeks after his rescue, Hauser apparently learned to read and write. He would later claim that he had been raised in a small room without light until an unknown man guided him to the outskirts of Nuremberg.

Stéphanie De Beauharnais

Wikimedia CommonsRumors spread that Hauser was a lost prince, or perhaps the son of Stéphanie de Beauharnais.

Observed by poet and professor Georg Friedrich Daumer, Hauser began to reveal more shocking details about his upbringing. He explained that he had been brought up in a prison during his early years but then also mentioned a detailed dream that involved him living in a castle.

Some residents, who believed that Hauser was a true feral person and “savant,” speculated that he may have actually been a lost prince, or perhaps even the son of Stéphanie de Beauharnais. Meanwhile, others simply thought that he was a fraud who was after fame and fortune.

To this day, Hauser’s true identity remains unknown. But one thing that is known is that he suffered a painful death. In his final years, there were many alleged attempts on his life by strange men, culminating in a fatal stabbing in 1833. However, some insisted that he had stabbed himself for attention, only to accidentally wound himself far more gravely than he had intended.

While it’s clear that Hauser enjoyed attention from others and almost certainly exaggerated his story, many still debate whether he was a talented con artist or a true feral person with severe mental illness. About 200 years later, we still don’t have the full answer and likely never will.
