One of the undisputed masters of 20th century visual art, Henri Matisse influenced generations of artists with a revolutionary style that featured flattened forms and an interpretive use of color. Along with several others, Matisse broke with the traditions of Impressionism, using vivid and often unnatural colors to convey emotional power rather than realistic appearance. Though Robert Capa was known predominantly for his impactful war photography, he was also a gifted portraitist and photographed Matisse—a close friend—in his studio in Nice in 1949.
