Matisse was one of the most celebrated painters of the 20th century who, even in his own lifetime, enjoyed a level of popularity envied by other artists. But in 1941, after a near-fatal operation for cancer, he decided to give up painting and sought a new way of drawing in colour. Scissors replaced a paintbrush and with the unique skill of a tailor, he set about creating his now famous cut-outs, which have yet to be rivalled for their originality and daring. To coincide with a major Tate Modern exhibition in April, Alastair Sooke presents a moving and intimate portrait, with contributions from the Tate's Nicholas Serota, biographer Hilary Spurling and Jacqueline Duheme, who worked with Matisse in the late 1940s at this critical turning point in his career.
