In the late 1950s, de Kooning's work shifted away from the figurative work of the women (though he would return to that subject matter on occasion) and began to display an interest in more abstract, less representational imagery. He became a US citizen on 13 March 1962, and in the following year moved from Broadway to a small house in East Hampton, a house which Elaine's brother Peter Fried had sold to him two years before. He built a studio near by, and lived in the house to the end of his life.
