An abstract, expressionist painter from the Netherlands, Willem de Kooning became an American Master of the 20th Century. Known for his Women series and Action paintings, the demand for his work continues to accelerate. Recently de Kooning’s Woman III sold for $137.5 million, becoming the second most expensive painting ever sold.
