Apache Kid
Inspiration for Tarzan
The young Apache Has-kay-bay-nay-ntayl (born in the 1860s) was a spy for Al Sieber, who was waging war against the Indians in the Arizona Territory.

When he was 20, his father was killed by a drunken soldier. He killed this man, and for the next ten years he was an outlaw and was known as Apache Kid. A long string of robberies, rapes and murders were attributed to him and his gang. Despite a reward of $5,000, Apache Kid was never caught, and it seems that he lived somewhere in Mexico until old age.

The young Edgar Rice Burroughs participated in a hunt for Apache Kid as a cavalryman in 1896. He may have found inspiration for his first novel about Tarzan, published in 1912, from this story.
