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.
