Despite this description there are quite a few "Super Heroes" without "super" powers. There are definately more than the 22 included in the ComicVine link (21 if you remove Captain America), as Hawkman and the first Atom are not mentioned. Who was the first costumed, crime-fighting Super Hero without super powers to appear in the 20th century in either the comics or newspaper funnies?
I'm looking for the first over-the-top Good Samaritan to appear in graphic form in the 20th century. A hero that is a regular person when they aren't saving the world... And yes, gadget users are included.
