David Alfaro Siqueiros constantly sought to express his revolutionary Marxist ideas using equally revolutionary means (airbrush, photographic projection) and new materials (nitrocellulose pigments, plywood). In his dynamic, figurative paintings and murals he developed a pictorial vocabulary and a sculptural treatment of form, working with a limited palette and dramatic light and shadow. Siqueiros began his studies at the Academia de San Carlos (Academy of San Carlos) in Mexico City beginning in 1911. A staunch communist and radical anti-fascist, Siqueiros interrupted his studies in 1914 to join the Mexican Revolutionary Army. While traveling in Europe from 1919 to 1922, he met his fellow countryman, the artist Diego Rivera (1886–1957). Back in Mexico City the two artists, together with José Clemente Orozco (1883–1949) founded the Mexican mural movement. A successful painter of monumental, political mural frescos, Siqueiros received public commissions in Mexico and executed mural projects in Los Angeles, New York, and South America during the 1930s. While in New York in the mid-1930s, he founded the Experimental Workshop for young artists, promoting collective practice and new techniques. One of the students was the young Jackson Pollock. In 1950 Siqueiros was one of the first Mexican artists to participate in the Venice Biennale.
