At first it was assumed that he had been raised like a half-wild human in forests, but during many conversations with Mayor Binder, Hauser told a different version of his past life, which he later also wrote down in more detail. According to this story, he had, for as long as he could think back, spent his life always totally alone in a darkened cell about two meters long, one meter wide, and one and a half high, with only a straw bed to sleep on and a horse carved out of wood for a toy.
He claimed that he had found bread and water next to his bed each morning. Periodically the water would taste bitter, and had been apparently drugged: drinking this would cause him to sleep more heavily than usual, and when he had awakened his straw had been changed, and his hair and nails had been cut. Hauser claimed that the first human being he ever had had contact with had been a mysterious man who had visited him not long before his release, always taking great care not to reveal his face to him. This man, Hauser said, had taught him to write his name by leading his hand. After having learned to stand and to walk he had been brought next to Nuremberg. Furthermore, the stranger allegedly had taught him to say the phrase “I want to be a cavalryman, as my father was” (in Bavarian dialect), but Hauser claimed that he had not understood what these words meant. – Kasper Hauser at wikipedia
What’s more interesting though, is that experts seem to agree that he must have made the whole story up. How long have we been taking in foundlings who’ve simply lost themselves?
I’m looking at you, “Piano Man”.
