The modern art collection includes works by the European masters Matisse, Gauguin, Monet, Picasso, Corrado Giaquinto, Giambattista Pittoni and Van Gogh. The museum's particularly strong collection of 20th-century German paintings includes the world's largest Max Beckmann collection, which includes "Christ and the Woman Taken in Adultery". In recent years, the museum has been actively acquiring post-war German art to complement its Beckmanns, such as works by Joseph Beuys, Gerhard Richter, Martin Kippenberger and others. The collection also includes Chuck Close's "Keith" (1970).
