Henri-Émile-Benoît Matisse (31 December 1869 – 3 November 1954) was a French artist, known for his use of colour and his fluid and original draughtsmanship. He was a draughtsman, printmaker, and sculptor, but is known primarily as a painter. Matisse is commonly regarded, along with Picasso and Marcel Duchamp, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting and sculpture. Although he was initially labelled a Fauve (wild beast), by the 1920s he was increasingly hailed as an upholder of the classical tradition in French painting. His mastery of the expressive language of colour and drawing, displayed in a body of work spanning over a half-century, won him recognition as a leading figure in modern art. Fauvism as a style began around 1900 and continued beyond 1910, the movement as such lasted only a few years, 1904–1908, and had three exhibitions. The leaders of the movement were Matisse and André Derain. Matisse's first solo exhibition was at Ambroise Vollard's gallery in 1904, without much success. His fondness for bright and expressive colour became more pronounced after he spent the summer of 1904 painting in St. Tropez with the neo-Impressionists Signac and Henri Edmond Cross. In that year he painted the most important of his works in the neo-Impressionist style, Luxe, Calme et Volupté. In 1905 he travelled southwards again to work with André Derain at Collioure. His paintings of this period are characterized by flat shapes and controlled lines, and use pointillism in a less rigorous way than before.
