Sonora Webster Carver did not have your average run-of-the-mill job. In 1923, responding to a newspaper ad, she accepted a job as a diving girl, where her duties included mounting a running horse as it reached the top of a forty-to-sixty-foot-tall tower. Atop the horse, she would plunge down to a deep tank of water, certainly earning her a place in circus history. Forty years after writing her autobiography entitled A Girl and Five Brave Horses, the book became the inspiration for Wild Hearts Can’t Be Broken, released on this day in 1991, which loosely depicted Carver’s life and watery, wild career.
