Saul Leiter (born 1923) is an American photographer and painter whose early work in the 1940s and 1950s was an important contribution to what came to be recognized as The New York School. His abstracted forms and radically innovative compositions have a painterly quality that stands out among the work of his contemporaries. Martin Harrison said, "He sought out moments of quiet humanity in the Manhattan maelstrom, forging a unique urban pastoral from the most unlikely of circumstances."
Willem de Kooning (April 24, 1904 – March 19, 1997) was a Dutch American abstract expressionist artist who was born in Rotterdam, the Netherlands. In the post-World War II era, de Kooning painted in a style that came to be referred to as Abstract expressionism or Action painting, and was part of a group of artists that came to be known as the New York School. -Wiki http://en.wikipedia.org/wiki/Willem_de_Kooning
