the Getty Centre in LA, linked to in the first post, is an art institute run on a multi billion dollar bequest left by oil man J Paul Getty.
You are perhaps thinking of the quite separate stock photo business Getty Images which is a public company that was started by a Getty descendant. The other big stock photo company is Corbis & that is privately owned by Bill Gates.
Ah, you are right. Sorry.
If you can't find the answer in APUG then it probably is a really dumb question.
