Finding beauty in junk

Although Kurt Schwitters (1887–1948) did not invent the technique or theory of collage, he was one of the greatest practitioners of it, raising it in his work to the level of an independent art form. The Cubists may have made art out of collage first, but for them it was intricately allied with painting, whereas Schwitters made collages for their own sake. They are some of the finest things in this rich and varied exhibition, which focuses on his years in Britain (1940–8), though the full range of his work, including a fascinating selection of paintings and sculptures, is also indicated in this typically large Tate display. Viewing it is a potentially exhausting experience, so best to be selective in what you choose to study.

Born in Hanover, Schwitters was closely associated with Dadaism, the radical and anarchistic art movement founded around 1915–16, though never a recognised member of the group, being too independent and insufficiently political.
