The great early 20C French artist took post-Impressionism into the colorful realms of fauvism
Henri-Émile-Benoît Matisse (1869-1954) was one of several contemporaries who took a hint from sythetism and added wild colors and strong patterns to create Fauvism ("wild beasts").
Matisse continued exploring these themes even when most artists were turning to Cubism, and later in life (with failing health) began assembling brightly colored collages of paper cutouts.
