José Victoriano González-Pérez (1887 – 1927), better known as Juan Gris, was a Spanish painter and sculptor born in Madrid who lived and worked in France most of his life. Closely connected to the innovative artistic genre Cubism, his works are among the movement's most distinctive. In 1906 he moved to Paris and became friends with Henri Matisse, Georges Braque and Fernand Léger. In Paris, Gris followed the lead of another friend and fellow countryman, Pablo Picasso. Gris began to paint seriously in 1910, developing at this time a personal Cubist style. At first Gris painted in the style of Analytical Cubism, a term he himself later coined, but after 1913 he began his conversion to Synthetic Cubism, of which he became a steadfast interpreter, with extensive use of papier collé or, collage. Unlike Picasso and Braque, whose Cubist works were practically monochromatic, Gris painted with bright harmonious colors in daring, novel combinations in the manner of his friend Matisse.
