Walter S. Rogers
Walter S. Rogers (born 1871) was the primary illustrator used by the Stratemeyer Syndicate for most of its series from the 1910s-1930s. Rogers was replaced in the 1930s by several other illustrators (Marie Schubert and J. Clemens Gretta for example) whose work was more modern and "edgy".
Rogers contributed illustrations in part or full for The Bobbsey Twins, Hardy Boys (Vol. 1-10), Tom Swift, Bunny Brown and His Sister Sue, Six Little Bunkers, Ted Scott Flying Stories, Motion Picture Chums, Motion Picture Boys, Motion Picture Girls, Outdoor Girls, X Bar X Boys, and others.
