Tarrare

Tarrare was a man living in the 1700s, who had an endless appetite due to unknown causes. In one case, he ate a meal intended for 15 people in a single sitting. He was also reported to have eaten live cats, snakes, lizards, and puppies, and swallowed eels whole without chewing. Despite his unusual diet, he was of normal size and appearance and showed no signs of mental illness other than what was described as an apathetic temperament. His endless hunger led him, while in a hospital, to eat piles of garbage, as well as trying to drink other patient’s blood and eat corpses from the morgue. After being suspected of eating a toddler, he was ejected from the hospital.
