Okay, the "Will Everett" version of Amazing Man isn't a true "Golden Age" character, not actually appearing until 1983 in the pages of All-Star Squadron #23 (July 1983).
And, as previously mentioned in a different thread, while there was a character named "Amazing-Man" who did appear in the Golden Age (debuting in 1939), that character was published by Centaur Publications and was created by William "Bill" Everett.
