This entry is a bit unorthodox in the sense that, while it is a twice told tale, it has some paradoxical elements that do not neatly fit in either Earth-One nor Earth-Two. So while these are golden and silver age Superman tales that are near parallel accounts, they may be a different pair of steel.
In each tale, there is a criminal who utilized advanced technology to circumvent Superman's ever watchful presence. But where did they get these fantastic device from?
As it turns out, Professor Amos Dunn in the 1960's and Professor William Enders in the 1950's had each carried a secret throughout Superman's life. And the secret was tied to the gimmick used by these goons.
Nevertheless, the parallels between these two stories seem to indicate that they were two branches of the same core tale. Oh, and the villains in the stories were eventually caught and never heard from forevermore until now.
