Charles Raab was an assistant for Milton Caniff on 'Terry and the Pirates' and for Alfred Andriola on 'Charlie Chan' in the 1930s. He took over the daily 'Adventures of Patsy' strip, when the original artist, Mel Graff, went on to do 'Secret Agent X-9' for King Features. Raab worked on the strip between 1940 and 1943. He either left the comic to go into military duty, or to start the strip 'Foreign Correspondent'. He did some romance, crime and sports stories for Hillman Periodicals in the late 1940s and early 1950s.
