Superman’s origin from the first appearance of Superman, Jerry Siegel and Joe Schuster, Action Comics #1, June 1938
When the vehicle landed on Earth, a passing motorist, discovering the sleeping babe within, turned the child over to an orphanage.
Attendants, unaware the child’s physical structure was millions of years advanced of their own, were astounded at his feats of strength.
When maturity was reached, he discovered he could easily:
Leap one-eighth of a mile; hurdle a twenty-story building…
Raise tremendous weights…
… run faster than an express train…
… and that nothing less than a bursting shell could penetrate his skin!
Early, Clark decided he must turn his titanic strength into channels that would benefit mankind.
And so was created…
Champion of the oppressed, the physical marvel who had sworn to devote his existence to helping those in need!
Kent had come from a planet whose inhabitants’ physical structure was millions of years advanced of our own.
Upon reaching maturity, the people of his race became gifted with titanic strength!
Incredible? No! For even today on our world exist creatures with super-strength! The lowly ant can support weights hundreds of times its own. The grasshopper leaps what to man would be the space of several city blocks.
