Abraham Rattner (July 8, 1895 – February 14, 1978) was an American artist, best known for his richly colored paintings, often with religious subject matter.

With the entry of the U.S. in World War I, Rattner was recruited to join the U.S. Army's American Camouflage Corps by that unit's commanding officer, Homer Saint-Gaudens, son of sculptor Augustus Saint-Gaudens (Behrens 2009).

He was sent to France, where he was "promoted to sergeant, put in charge of camouflage research, and served at the front in the Second Battle of the Marne, Château-Thierry, Belleau Wood, and on the Hindenberg Line.

Although while living in Paris, he had met and studied the paintings of Claude Monet, his work is generally closer to that of Georges Rouault and Pablo Picasso.

[3] He designed the stained glass east wall which dominates the interior of the Chicago Loop Synagogue (1960),[4] described by architectural critic Brian de Breffny as "[p]erhaps the most beautiful synagogue interior in the United States.
