In the wild west who called himself "The Law West of the Pecos"?

Phantly Roy Bean, Jr. (1825 – March 16, 1903) was an eccentric American saloon-keeper and Justice of the Peace in Val Verde County, Texas, who called himself "The Law West of the Pecos". According to legend, he held court in his saloon along the Rio Grande on a desolate stretch of the Chihuahuan Desert of southwest Texas. After his death, Western films and books cast him as a hanging judge, although he is known to have sentenced only two men to hang, one of whom escaped.

For much of his life Bean moved from town to town (in Mexico, Southern California, New Mexico, and Texas) getting into and fleeing from one scrape after another, killing at least two men in duels. During the Civil War he first served with Confederate regulars and then was a blockade runner in Texas, becoming so prosperous that he could live married in San Antonio for some 16 years at ease. In 1882 he moved on, west of the Pecos River, and set up a saloon, the Jersey Lilly, next to a railroad line through Dead Man’s Canyon. He named the site Langtry (after the actress Lillie Langtry) and eventually established himself as justice of the peace, with the approval of the Texas Rangers. He knew neither law nor court procedure and became celebrated for his rulings,
