David Alfaro Siqueiros.

Siqueiros, David Alfaro (dävēt̲h̲′ älfä′rō sēkā′rōs), 1896–1974, Mexican painter, b. Chihuahua. Siqueiros was among Mexico's most original and eminent painters. His career as an artist was always related to his vigorous socialist revolutionary activities. He enlisted in the Batallón Mamá (Baby's Brigade) in the Carranza army and at 17 was a staff officer. As military attaché at the Mexican legation in Paris (1919–21), he came into contact with stimulating contemporary artistic movements. Upon his return to Mexico in 1922, he became a leader of the Syndicate of Technical Workers, Artists, and Sculptors and a founder of the magazine Machete, which expounded the principles of a new national people's art. After frequent imprisonment for political activities and extensive travel abroad, Siqueiros served as an officer in the Spanish republican army (1938). [ABSTRACT FROM PUBLISHER]
