I'm having a discussion on another forum about the origins of the term "Super-Hero". Now, it appears generally assumed that it's derived from the character Superman, considered the first true Superhero. But I seem to recall someone, probably here, mentioning that the term predated Superman, specifically that it was used as a tag line on a Doc Savage novel or comic. Is this true? Or is my memory playing tricks on me and it is derived from Superman?
Thanks for the help.
