Abraham Rattner (July 8, 1895 – February 14, 1978) was an American artist, best known for his richly colored paintings, often with religious subject matter. During World War I, he served in France with the U.S. Army as a camouflage artist.
He initially intended to be an architect, in pursuit of which he studied at George Washington University. Deciding instead to concentrate on painting, he then went on to study art at the Corcoran School of Art and the Pennsylvania Academy of the Fine Arts. Rattner lived in Paris from 1920 until 1940, when he returned to New York City. He became known for his rich use of color and surrealist aspects of his work, which often pertained to religion.
