American painter, born in North Tonawanda, New York. He is known for Minimalist paintings, sometimes with shaped canvas. Red Wall (1965, Tate) was inspired by the loft architecture of New York and was made from standardized sheets of masonite painted with a spray gun. The brick-like colour is intended to remind the spectator of ordinary objects. Mangold sometimes divides his canvases with simple geometric shapes such as squares and circles but the results are rarely perfectly symmetrical. For Roberta Smith (New York Times, 29 September 1989) his paintings brought to mind the qualities of a Renaissance altarpiece.
