Estimated Worth: $25 Million

Though Chuck Close may be confined to a wheelchair due to a spinal artery collapse that left him with limited motion due to severe paralysis, he continues to churn out amazing large-scale portraits that are highly sought after. With works selling anywhere from $150,000 to $5 million, the demand for Close's work doesn't show any signs of slowing, but his most recent art "project" may change all that. In 2011, Close and several other artists sued the New York outlets of Christie's and Sotheby's, two of the art world's biggest auction houses for systematic royalties fraud. And though this might not have been the best move business wise, but you got to give it to Chuck for publicly giving them the finger.
