Superman is a comic book superhero, originally created by American writer Jerry Siegel and Canadian artist Joe Shuster and published by DC Comics. Created in 1932, and rejected by a number of publishers, the character first appeared in Action Comics #1 (June 1938). With a premise that taps adolescent fantasy, Superman is born Kal-El on the alien planet Krypton, before being rocketed to Earth as an infant by his scientist father moments before the planet's destruction. Adopted and raised by a Kansas farmer and his wife, the child is raised as Clark Kent, and imbued with a strong moral compass. Upon reaching maturity the character develops superhuman abilities, resolving to use these for the benefit of humanity. With the success of his adventures, Superman helped to create the superhero genre and establish its primacy within the American comic book.[1] Superman is today widely considered to be both one of the most famous and popular comic book superheroes of all time,[2] and an American cultural icon

Superman's first appearance was in Action Comic #1 1938.  The magazine featured Superman doing a superhuman feat on the cover.
