Brad Edgerton

Larry Helmerich's boss. There's a great story about him hiring Larry:
Larry had been out in Los Angeles on a whim, and had interviewed with Brad pretty much again on a whim. Brad offered Larry a job, to start in a few weeks, so Larry went back home, arranged for moving vans, and moved out here, with just a few dollars left in his pocket...and when he showed up for work on the first day, they had never heard of him, and Brad was on vacation, incommunicado, for two weeks!
But they said that hiring Larry and not mentioning it to H.R. was something that Brad might do, so they told him to make himself at home and get started. I think they even advanced him some money from his paycheck.
Still made for an interesting first two weeks, though.
