Don Dohler created the comics character Pro Junior in high school and later used it as a mascot for his fanzine Wild!, that was published between 1961 and 1963. Jay Lynch, Skip Williamson and Art Spiegelman were frequent contributors to this fanzine, so when Jay Lynch developed into underground comix in the 1970s, he resurrected the character for a strip he did with Robert Crumb. Denis Kitchen's Krupp Comic Works produced Pro Junior Comics in 1971, and invited 22 other comic artist to contribute their own comic about Pro Junior, such as R. Crumb, Pete Poplaski, Trina Robbins, Art Spiegelman, Evert Geradts, Denis Kitchen, Joel Beck and Bill Grifith. Don Dohler did one other one-page strip for Lynch's one-shot Roxy Funnies in 1972.
After his stint in the underground comix scene, Dohler founded Cinemagic Magazine in 1972. He sold the title to Starlog in 1979, and he did another magazine and several books on filmmaking and special effects. Dohler became an independent movie writer, director and producer. Besides his work in the cinema field, he was a newspaper editor since 1986.
