Pawnee Bill

William Gordon Lillie worked as a teacher, interpreter, and advocate for the Pawnee people who were relocated to Oklahoma.

 His lifelong relationship with the tribe earned him the name Pawnee Bill. He was hired to coordinate the Pawnee actors in Buffalo Bill's first tour. Five years later he went on the road with his own show called Pawnee Bill's Wild West. As time went by, he added Japanese acrobats and Arabian jugglers to the show. In 1908 he again joined Bill Cody, this time as an equal, as they formed "Buffalo Bill's Wild West and Pawnee Bill's Great Far East." Lillie's wife May (pictured) was a rider and sharpshooter in his show while still a teenager.
