Chuck Close (born 1940) is an American photorealist specializing in close-up portraits and self-portraits. Close is one of the very few modern realists or photorealists who focus on the human face.
In 1988, in mid-career, Close was paralyzed due to a blood clot in his spinal column. He regained partial use of his arms, and was able to return to painting after developing techniques which allowed him to work from a wheelchair.
Make note of the dimensions of the original works when you view Close's work on the Internet. His portraits are typically enormous, and immensely powerful in person.
