With the wealth of well over $25 million, the legendary painter Chuck Close easily makes it to this list. Initially achieving fame with his exceptionally large portraits based on photographs, he expanded his efforts to an endless number of artistic mediums, including prints, tapestries etc. Wheelchair bound since 1988 due to a spinal artery collapse, his creative urge never subsided and he continued to produce pieces of superb quality, always keeping in demand for his work which doesn't show any signs of slowing. In 2011, he gained additional media exposure when, with a group of other artists, he sued Christie’s and Sotheby’s auction houses for allegedly violating the 1977 California Resale Royalty Act.
