There were a lot of major league Disney talents who worked on the Mansion project at one time or another while it was in development but who don't automatically come up in conversation like the Big Seven do (B7 = Anderson, Crump, Gracey, Davis, Atencio, Coats, and—if we remember that we have ears as well as eyes—Buddy Baker). At least, those are the Big Seven in my mind. Some would put Blaine Gibson on the short list as well. Note that I'm only talking here about the creative and conceptual guys, not the engineering and technical guys, many of whom deserve trophies of their own. Anyway, some of the talents on the creative and conceptual end simply didn't contribute material in sufficient quantity to make them haunted household names; nevertheless, they deserve recognition and appreciation if you're a Mansion fan. One of these is Sam McKim.
Quick on the Draw
If the name "Sam McKim" is not familiar—well, there's no point in trying to review his whole career here. That's what other Disney sites are for.
(I haven't counted, but gosh, there must be at least a dozen blogs and websites on the internet dedicated to some aspect of the Disney creative legacy.) McKim is a Disney legend. You can read about him HERE. More than one source claims he's best known for his huge souvenir park maps from the 50s and 60s, and for sure those maps are a source of endless delight. It was (and is) great fun to pore over them with a magnifying glass, discovering all the whimsical details McKim put there. There's a good article on these maps HERE.
It may be true that McKim is most famous for those maps among us
recent in 2008. The superb McKim sketch seen here graced the 1961—65 maps, and it is the only one that has ever been architecturally accurate.
Outside the House
Okay, what about the Mansion? Well, here's a pic of Sam as one of the onstage panel of Imagineers at the 30th anniversary celebration in 1999 (which incidentally was far and away the best HM Anny celebration to date).
