He began his comics career in 1939, during the period fans and historians call the Golden Age of Comic Books, beginning at Victor A. Fox's Fox Publications. There he penciled and inked the six-page "Flick Falcon" feature in "Fantastic Comics" #1 (Dec. 1939). He continued on that feature through issue #8 (July 1940 ), by which time the hero's name and the feature's title had been changed to "Flip Falcon". He drew the features "Blast Bennett" and "Sorceress of Zoom" for Fox's "Weird Comics", and did stories for Fiction House's "Planet Comics" and "Fight Comics". Beginning with "Silver Streak Comics" #11 (June 1941), he worked on some of the earliest stories of Lev Gleason Publications' 1940s superhero Daredevil (unrelated to Marvel Comics' Daredevil), helping lay the foundation for a character that would go on to a celebrated run in his own title under Charles Biro.
