After reading some comics today and thinking about one of my previous questions, I was wondering "When was the first use of secret identities in Comics?"
The earliest one I can think of is Superman from his 1938 debut, but I can't tell anywhere if this is the first.
This is what Wiki has to say on the matter:
The use of secret identities dates back to the early 20th century with characters such as the Scarlet Pimpernel, the Lone Ranger, and Zorro. Starting in the 1930s, the concept of a crime-fighters, superheroes, and vigilantes (and their adversaries) adopting secret identities became more widespread in dime novels, pulp magazines, comic books, old-time radio dramas, movie serials, and other popular fiction. Such characters remain popular to this day.
So it might be in the 1930s, but I don't know for sure or when/who was first? IT strikes me that if Superman and Batman debuted in/around 1938 with secret identities that's quite late to be called the 1930's.
