Siegel: If youre interested in what made Superman what it is, heres one of the keys to what made it universally acceptable. Joe and I had certain inhibitionswhich led to wish-fulfillment which we expressed through our interest in science fiction and our comic strip. Thats where the dual-identity concept came from, and Clark Kents problems with Lois. I imagine there are a lot of people in this world who are similarly frustrated. Joe and I both felt that way in high school, and he was able to put the feeling into sketches.
