26 March 1940 in Düsseldorf) is a German painter.
From 1980 to 2005, he was a Professor of Painting at the Kunstakademie Münster (University of Fine Arts Münster).
He is known as a master of the color field style of abstract painting, closely related to abstract expressionism, in which he creates tension between a defined surface structure, his own method of applying paint to a canvas, and the relationship of various shades of white or color to each other in their placement as part of a composition on the flat plane of a canvas.
In 1986 and 2008, he was awarded the Konrad-von-Soest Prize for Visual Arts by the Landschaftsverband Westfalen-Lippe (Landscape Society Westphalia-Lippe).
