In 1943, Cleophis Hill Williams was a teenager visiting her mother who had moved to Las Vegas. For most of her young life she had lived with her parents in Muskogee, Oklahoma and Paul Spur/Douglas, Arizona. The same year that she visited Las Vegas, she met her future husband Tom Williams, with whom she had nine children, all born and raised on the Westside. Tom worked construction and built their first home on G Street. For Cleophis, she focused her life on raising her children and, whenever possible, finding some precious time to read.

While offering anecdotes on Southwest Gas Company’s early years—including its flirtation with a nuclear bomb and owning a casino; its purchase of a Kingman, Arizona, ranch with an underground salt dome, and its involvement with the formation of Boyd Gaming—this oral history also reveals Bill Jr.’s role in applying his knowledge of natural gas infrastructure to promote extensive education about building codes, infrastructure, and engineered systems. In particular, Bill discusses EduCode, the internationally recognized, week-long building code institute held annually in Las Vegas that originally began more than twenty-five years ago and has since attracted worldwide participation. While Bill does not teach at the institute, he has helped organize the course since its inception and has been a consistent supporter.
