I came across a really great slideshow from Forbes that lists the world's top billionaire art collectors, including Eli Broad, Francois Pinault, and members of the Lauder family.

Art collection: $750 million
Hedge fund titan has been a prolific buyer of art, said to have spent upward of $500 million in recent years. He paid David Geffen a record $137 million for a de Kooning, a month after having paid him $63.5 million for another de Kooning. He agreed to pay $139 million for a Picasso, but the sale fell apart after seller Stephen Wynn put his elbow through the painting. Also owns Damien's Hirst's 13-foot shark (pictured); encased in formaldehyde, it reportedly rotted and was replaced. His SAC Capital bought a stake in Sotheby's auction house earlier this year.
