Jerry Siegel quotes
One night, when all the thoughts were coming to me, the concept came to me that Superman could have a dual identity, and that in one of his identities he could be meek and mild, as I was, and wear glasses, the way I do. The heroine, who I figured would be some kind of girl reporter, would think he was some kind of worm; yet she would be crazy about this Superman character who could do all sorts of fabulous things. In fact, she was real wild about him, and a big inside joke was that the fellow she was crazy about was also the fellow whom she loathed.
