For example, from Graves' The Greek Myths:

"Hermes also helped Perseus, giving him an adamantine sickle with which to cut off Medusa's head."

Taking these existing words and adding the -ium suffix common to many elements is kind of logical and there are uses in sci-fi stories that pre-date Marvel, as Brian said.

For example, this story from 1941:

(Edited to add: But in Marvel comics, it's with Ultron that it first appeared, once again as Brian says).

I promised myself I wouldn't interact in this particular thread no more, but I crumbled and read this.

That anybody could possibly state that Roy Thomas (!) is "probably second only" to Stan Lee in "beloved characters created" while completely ignoring the existence of a certain fellow named Jack Kirby is truly something I'd never thought I could possibly be exposed to in a comics knowledgeable context.

Now I'm out, I promise. You guys celebrate, this era is definitely your time to shine.

  

Small thing, a detail really.

Wolverine has been on film for 25 years now. Just now, at this very moment when Wein is no longer with us and a Wolverine movie is coming out, the guy decided to approach.

Totally normal, ethical behavior. Saying that with a straight face is almost admirable in a way.

Kudos.

Yes, that was addressed in the article.  Prior to Logan, 20th Century Fox chose not to acknowledge comic creators in the film credits.  The Logan credits thanked many creators who worked on the stories that inspired the film, including:

Byrne

Claremont

Cockrum 

Kyle

Liu

Romita

Silvestri

Wein 

Also, in the article Thomas pointed out “Wolverine was appearing in films produced by 20th Century Fox, and Marvel didn’t have involvement...Deadpool/Wolverine is a Marvel movie, so they decided to look at my claims.”
