The Kunstmuseen Krefeld is an art museum in Krefeld, Germany. It is particularly dedicated to modern and contemporary art. Three houses constitute the museum—the Kaiser Wilhelm Museum, Haus Lange and Haus Esters. Since the late 1950s, the museums have risen to international prominence. Katia Baudin, former deputy director of the Museum Ludwig in Cologne, has headed the museums since 1 September 2016.

Pieter Cornelis Mondriaan, after 1906 known as Piet Mondrian, was a Dutch painter and art theoretician who is regarded as one of the greatest artists of the 20th century. He is known for being one of the pioneers of 20th-century abstract art, as he changed his artistic direction from figurative painting to an increasingly abstract style, until he reached a point where his artistic vocabulary was reduced to simple geometric elements.
