Leo Castelli, Pope of Pop

Leo Castelli [5'6"] had a reputation for being a dapper dresser. He also had a rep for being the man who single-handedly "revolutionized the status of the artist in America and changed all the rules of the art market," according to Leo and His Circle, the forthcoming bio by Annie Cohen-Solal.

Here's a take by some artist buddy of his:

Who says short guys shouldn't wear double-breasted suits?

Google Image Search the guy. In almost every shot, he's either off-center at the bottom of the frame...

Sitting down while famous painters tower over him...

Surrounding himself with the very tall...

Behind, beneath or otherwise dwarfed by one of his gallery's large works of art...

Or trying his best to appear shorter than even himself...

"I don't like it when people say that I'm diminutive. I'm small, but not diminutive."

--Leo Castelli
