Agreed. I mean, the article literally uses his nickname ("the King") to refer to him. How could anyone who isn't being properly recognized have the well known nickname "King"?
Hmm, I'm not a huge comic fan (only recently started buying some, again) and I've never heard the nickname. I knew the name Jack Kirby, of course, but I have to agree that the names Lee and Kirby didn't really tell me a lot before Wikipedia was around (and/or the MCU started).
