George Reeves (Jan 6, 1914–Jun 16, 1959)
George Reeves was an American actor, best known for playing the role of Superman primarily on television in the 1950's on the show The Adventures of Superman.
In the year 2230, a film reel of the famous TV show from Earth-Prime is shown by a group of archaeologists on a "Galaxy News" broadcast to prove that Superman was in fact Clark Kent, not Morgan Edge or Bruce Wayne as it was generally accepted before (S No. 400, Oct 1984: ""The Legend From Earth Prime!")
