Superman’s Parents?

Within the Superman lexicon, every fan knows that Clark Kent had parents on planet Earth and parents on his home planet. On Earth, Superman transformed into his alter-ego Clark Kent and his parents were named Jonathan and Martha. However, it seems as though this was not always the case. Well, according to Adventures of Superman, anyway. In the very first episode entitled “Superman on Earth” which was shot in 1952, Clark Kent’s parents are shown to be named Eben and Sarah. Apparently, within the comic book world of Superman, the characters did not yet have consistent names. The names Sarah and Eben were shown in the 1942 novel called “The Adventures of Superman and in the first Superman short film. However, the two characters were seen as minor until the Superboy comics some time later.
