It has to be said...
Herb Trimpe did not develop Wolverine. Wolverine was co-created by Len Wein and John Romita, Sr.. Herb did draw Wolverine's first appearance, but even Herb tells people that he had nothing to do with Wolverine's creation, and he should know.
Plus... it was Dave Cockrum who designed what Logan looked like, and it's his Logan design which is used in the movies, not John, Sr.'s "cat suit." That doesn't take anything away from what John, Sr. did, it just states the facts.
I hate to write what could be perceived as a negative comment here when this is a big step forward, but facts do matter. Not saying that Mr. Wein doesn't know what happened (because he does), or that he was trying to give credit where credit wasn't due. He was just quoting the box. If only the box knew what it was talking about, we wouldn't have to start all over again where Wolverine's credits are concerned.
Well, Mr. Cadigan, in response, I'm obliged to say you're right...and you're wrong.
While the original Wolverine visual was indeed co-created by myself and the talented John Romita Sr., the credit on the DVD box reads Wolverine character developed by Len Wein & Herb Trimpe. That's developed, not created. And since Herb drew Wolvie's entire first appearance, from the last panel of Incredible Hulk #180 through the first couple of pages of Hulk #182, I would say he did indeed develop the character, how he stood, how he moved, his expressions, attitudes, all critical aspects of Wolverine's natural evolution.
I certainly don't begrudge Herb the credit. Why should you?
