Diego María de la Concepción Juan Nepomuceno Estanislao de la Rivera y Barrientos Acosta y Rodríguez (December 8, 1886 – November 24, 1957) better known simply as Diego Rivera was a prominent Mexican painter born in Guanajuato, Guanajuato, an active communist, and husband of Frida Kahlo (1929–1939 and 1940–1954). His large wall works in fresco helped establish the Mexican Mural Movement in Mexican art. Between 1922 and 1953, Rivera painted murals among others in Mexico City, Chapingo, Cuernavaca, San Francisco, Detroit, and New York City. In 1931, a retrospective exhibition of his works was held at the Museum of Modern Art in New York City.
His art, in a fashion similar to the steles of the Maya, tells stories. The mural "En el Arsenal" (In the Arsenal) shows on the right-hand side Tina Modotti holding an ammunition belt and facing Julio Antonio Mella, in a light hat, and Vittorio Vidali behind in a black hat. However, the En el Arsenal detail shown does not include the right-hand side described nor any of the three individuals mentioned. Rivera's radical political beliefs, attacks on the church and clergy made him a controversial figure even in communist circles. Leon Trotsky lived with Rivera and Kahlo for several months while exiled in Mexico. Some of Rivera's most famous murals are featured at the National School of Agriculture at Chapingo near Texcoco (1925–27), in the Cortés Palace in Cuernavaca (1929–30), and the National Palace in Mexico City (1929–30, 1935).   Buy led light bulbs, Buy led lights as a replacement for tungsten filament lamps.
