David Alfaro Siqueiros

David Alfaro Siqueiros (born José de Jesús Alfaro Siqueiros; December 29, 1896 – January 6, 1974) was a Mexican social realist painter, best known for his large public murals using the latest in equipment, materials and technique. Along with Diego Rivera and José Clemente Orozco, he was one of the most famous of the "Mexican muralists".

Siqueiros was a member of the Mexican Communist Party. Although he went to Spain to support the Spanish Republic against the forces of Francisco Franco with his art, he volunteered and served in frontline combat as a Lieutenant Colonel in the Army of the Republic through 1938 before returning to Mexico City. In 1940, he led a failed assassination attempt on Leon Trotsky in which Trotsky's 14-year-old grandson was shot and American communist Robert Sheldon Harte was executed. After spending several months on the run from Mexican authorities disguised as a peasant, Siqueiros was eventually apprehended in Jalisco, although he would never be brought to trial and was freed shortly.

By accordance with Spanish naming customs, his surname would normally have been Alfaro; however, like Picasso (Pablo Ruiz y Picasso) and Lorca (Federico García Lorca), Siqueiros used his mother's surname. It was long believed that he was born in Camargo in Chihuahua state, but in 2003 it was proven that he was born in the city of Chihuahua after the discovery of his birth certificate, but grew up in Irapuato, Guanajuato, at least from the age of six. According to Victor Mendoza Magallanes, he was born in Santa Rosalia in modern day Camargo, Chihuahua. One source says that the discovery of his birth certificate in 2003 was by a Mexican art curator the following year by art critic Raquel Tibol, who was renowned as the leading authority on Mexican Muralism and who had been a close acquaintance of Siqueiros. Although there hasn't been any evidence to prove this. Siqueiros changed his given name to "David" after his first wife called him by it in allusion to Michelangelo's David.
