Peter, the Wild Boy

Peter, the Wild Boy, a savage creature of 13 years of age, found in 1725 in a forest of Hanover, who was accustomed to walk on all fours, and climb trees like a squirrel, living on wild plants, grass, and moss, and who could not be weaned from these habits, or taught to speak more than a syllable or two; he wore a brass collar with his name on it; at length refused all food, and died in 1786.
