Roland Davies studied to be a lithographer, but became an illustrator instead, starting with several cinema posters and illustrations for magazines Autocar and Motor Cycle. In 1928, he began working for Modern Boy, where he drew illustrations and covers. He finally made his debut in comics in March 1932 with 'Come on, Steve!', which appeared in the Sunday Express. This pantomime comic was a success and Davies founded a studio in 1936 to make an animated version of it.
Davies drew series like 'Whoopee Hank' and 'Contrary Mary' for The Beano in 1938. Soon, he also took on comics in the realistic genre, such as 'Sexton Blake', 'Dixon of Dock Green', 'Norman and Henry Bones' and 'Red Ray the Space Racer'. For a female audience, he illustrated 'Jill Crusoë' in School Friend from 1950 to 1959. He also drew 'Pete Madden' in Knockout and did a version of 'Beetle Bailey' for TV Comic from 1965. In 1970, Roland Davies left the comics field and started painting.
