[Downunder Dan]

Carl Lyon was a commercial artist who turned his hand to comics during the golden age. He did a lot of work for Frank Johnson and apparently originated the popular Avian Tempest in Little Trimmer. As well as Devil Doone, he worked on other detective comics including Tim O'Hara (originally a newspaper strip, later collected in comic books) and the Astounding Mr Storm. He also wrote and illustrated children's books. He became the assistant to Stan Cross on the popular and long-running Wally and the Major, taking the feature over when Cross retired. He worked exclusively on this strip until 1979 when Lyon retired, and sadly only lived for another three years.
