José Clemente Orozco (November 23, 1883 ââ¬â September 7, 1949) was a Mexican caricaturist and painter, who specialized in political murals that established the Mexican Mural Renaissance together with murals by Diego Rivera, David Alfaro Siqueiros, and others. Orozco was the most complex of the Mexican muralists, fond of the theme of human suffering, but less realistic and more fascinated by machines than Rivera.
