(b Paris, 8 Dec. 1881; d Avignon, 23 June 1953). French painter, printmaker, and writer. His early work was Impressionist in style, but in 1909 he took up Cubism. In 1912 he was among the founders of the Section d'Or group and in 1912 he wrote with Metzinger the book Du Cubisme (an English translation, Cubism, appeared in 1913). This was the first book on the movement and it remains Gleizes's main claim to fame.
