In 1957 Otto Binder recruited Schaffenberger to DC to work on the Superman family. He stayed at DC for the next 30 years, making an especially large contribution to the development of Lois Lane. In this capacity, he was the lead artist on the "Superman's Girl Friend, Lois Lane" series for the entirety of its first decade. Indeed, Schaffenberger's rendition of Lane became cited by many as the "definitive" version of the character, and Schaffenberger was often asked by DC editor Mort Weisinger to redraw other artists' depictions of Lois Lane in other DC titles where she appeared. Catwoman made her first appearance in the Silver Age of Comic Books in "Superman's Girl Friend, Lois Lane" #70 (Nov. 1966) in a story drawn by Schaffenberger. In issue #80 (Jan. 1968), Schaffenberger updated the character's fashions to a then-more contemporary look.
