Professor Roberts was the mentor and employer of Darrel Dane, better known as Doll Man. He and his daughter Martha were present when young Dane conducted the experiment that turned him into Doll Man. He was involved in several of Doll Man's earliest adventures as well. In those days, Dr. Roberts sometimes packed a concealed handgun, with which he killed one villain. At other times he lacked a handgun, and regretted it.
There was at least one period of time in the 1940s during which Professor Roberts no longer knew the secret identity of Doll Man.
- Doctor Roberts could fly at least two types of amphibious airplanes.
