Or, as I always like to think of him, "Amazingly Brittle Man". I'm sorry! That joke just kills me every time; of course, it had the same effect on Amazing Man...
Don't be deceived; there was no Amazing Man in comic books during World War II. The "original Amazing Man" is a 1983 retcon creation of Roy Thomas, The Man With The Tachyonic Brain. Will Everett was basically Jesse Owens getting superpowers (which is more interesting than Bruce Jenner getting superpowers, but still less interesting than Mark Spitz getting superpowers).
I'm pretty sure he was mostly created as a backstory for Amazing Man II, his grandson Will Everett II. Neither of them got a lot of airtime, as they never caught the public's imagination. They each had the power to mimic the properties of whatever substance they had most recently touched, which not only sounds more like a horrible disease than a superpower, it's so abstract as to seem suspiciously like a ... MARVEL power. Isn't there a Marvel villain who does that? Mimic? Mimeo? Zeerox?
I don't remember how Amazing Man I died, but everyone remembers how Amazing Man II died. The Mist's daughter tricked him into becoming glass, then shattered him while making the "Amazingly Brittle Man" joke.
