Question: David Alfaro Siqueiros was a Mexican muralist who designed the Polyforum Cultural Siqueiros and was a member of what political party?
Context: Mario Orozco Rivera (January 19, 1930 – November 20, 1998) was a Mexican muralist and painter, a later proponent of Mexican muralism, and whose work was particularly influenced by David Alfaro Siqueiros.  He created a number of murals, mostly in the state of Veracruz before becoming an assistant to Siqueiros, directing the Taller Siqueiros in Cuernavaca and working with the artists on projects such as the Polyforum Cultural Siqueiros.  While preferring mural work, which he considered less commercial, Orozco Rivera also created oils and sculptures.  Many of these works were exhibited in Mexico and abroad and can be found in many major collections.  His work received recognition in various countries. Cordelia Urueta Sierra (b. September 16, 1908 (Coyoacán)– d. November 3, 1995 (Mexico City)) was a Mexican artist best known for her use of color and abstraction but still retaining frequent reference to the human form.  She was born into an intellectual and artistic family, related to painter David Alfaro Siqueiros and educator Justo Sierra.  Her father, writer and diplomat Jesús Urueta Siqueiros, died when she was eleven with her health becoming quite poor afterwards.  She began drawing when she was a child, mostly portraits with Dr. Atl noticing her talent.  She did not have extensive formal training but became an art teacher, meeting a number of contemporary Mexican artists, including her husband Gustavo Montoya.  After a time in Paris and New York, she returned to Mexico permanently in 1950 to dedicate herself to painting, exhibiting extensively in Mexico and abroad mostly in the 1950s and 1960s.  She was offered the Premio Nacional de Arte but rejected it. Tropic or Trópico is a 1945 painting by Spanish artist Josep Renau.  Renau executed the painting during his exile in México, while he collaborated with Mexican muralist painters such as David Alfaro Siqueiros.  The painting represents a landscape, probably a Mexican natural space.  Three vultures surround a fish skeleton on the lower right side of an uninhabited landscape.  The scene evokes the desolation and destruction of humankind provoked by the wars of the 20th century, in the precise year of the end of World War II, which left a death toll of 60 million people. Arturo Moyers Villena (January 2, 1930 – February 3, 2013) was a Mexican muralist and painter, whose work was influenced by David Alfaro Siqueiros.  Many of his mural works are exhibited in government buildings or cultural institutions. The World Trade Center Mexico City, also still commonly called by its former name, Hotel de México, is a building complex located in south-central Mexico City, Mexico.  Its most famous and recognizable feature is the 52-story, 207 m (670 ft) high Torre WTC, the third tallest building in Mexico City (including antenna), or fourth when measured by its 191 m (587 ft) roof height.  When talking about the World Trade Center México, one usually is referring to the uniquely shaped tower.  The complex also includes a convention center, cultural center, parking facilities, a multi-screen cinema, a revolving 45th-floor luxury restaurant, and shopping center with Sears as an anchor tenant.  It will also include a 22-floor hotel, which is currently under construction.  Located on Avenida de los Insurgentes, the complex is served by the Polyforum station of the Metrobús Bus rapid transit system, located a few meters away.  The station is named after the Polyforum Cultural Siqueiros, a part of the WTC complex. The Mexican Secretariat of Public Education (in Spanish "Secretaría de Educación Pública", "SEP") is a federal government authority with Cabinet representation and responsibility for overseeing the development and implementation of national educational policy and school standards in Mexico.  The Secretariat has several buildings distributed all over the country but its main offices, initially confined to the Old Dominican Convent of the Holy Incarnation in the oldest borough of Mexico City, have extended to the House of the Marqués de Villamayor, (also known as the "Casa de los adelantados de Nueva Galicia", built in 1530), the Old House of don Cristóbal de Oñate, a three-times Governor and General Captain of New Galicia (also built in 1530) and the Old Royal Customs House (built in 1730-31).  Some of the buildings were decorated with mural paintings by Diego Rivera and other notable exponents of the Mexican muralist movement of the 20th century David Alfaro Siqueiros, Raul Anguiano, Manuel Felguerez. Guillermo Ceniceros (born May 7, 1939) is a Mexican painter and muralist, best known for his mural work in Mexico City as well as his figurative easel work.  He began his mural painting career as an assistant to mural painters such as Federico Cantú, Luis Covarrubias and then David Alfaro Siqueiros who was a mentor and a key influence.  Ceniceros is the most notable of Siqueiros' assistants.  While he has experimented with abstract expression, his easel work mostly classifies as figurativism and is influenced by the geometrical construct of Mexican muralism.  He has had over 300 individual and collective exhibitions in Mexico and the International stage.  His work has been recognized by the Mexican Ministry of Culture and several of its institutions.  He has painted over 20 large scale Mural Paintings with some of the most notable being the large scale work for the Legislative Palace of San Lazaro (Mexico's Legislative Building) as well as his murals in the Metro Subway System.  He is a member of the Salón de la Plástica Mexicana.  In 1995 the State of Durango, Ceniceros' native state, opened to the public the Guillermo Ceniceros Art Museum within the oversight of the Ministry of Culture.  Ceniceros has been reviewed by notable critics such as Berta Taracena, Raquel Tibol, Alaide Foppa, Graciela Kartofel, José Angel Leyva and Eduardo Blackaller among others.  There are several publications about his work including a vast review of his art life endeavors developed by the Ministries of Culture of Durango and Nuevo León.  He is married to the artist Esther González and lives in his studio house in the Colonia Roma of Mexico City. David Alfaro Siqueiros (born José de Jesús Alfaro Siqueiros, December 29, 1896, in Chihuahua – January 6, 1974, in Cuernavaca, Morelos) was a Mexican social realist painter, better known for his large murals in fresco.  Along with Diego Rivera and José Clemente Orozco, he established "Mexican Muralism."  He was a Marxist-Leninist in support of the Soviet Union and a member of the Mexican Communist Party who participated in an unsuccessful attempt to assassinate Leon Trotsky in May 1940. The Polyforum Cultural Siqueiros is a cultural, political and social facility located in Mexico City as part of the World Trade Center Mexico City.  It was designed and decorated by David Alfaro Siqueiros in the 1960s and hosts the largest mural work in the world called “La Marcha de la Humanidad.”  The building has a theatre, galleries and more, but the main focus is the Forum Universal, which contains the interior portion of Siqueiros' mural work.  Visitors can experience the mural while standing on a rotating stage, listening to Siqueiros narrate. Fanny Rabel (August 27, 1922 in Poland – November 25, 2008 in Mexico City), born "Fanny Rabinovich",was a Polish-born Mexican artist who is considered to be the first modern female muralist and one of the youngest associated with the Mexican muralism of the early to mid 20th century.  She and her family arrived to Mexico in 1938 from Europe and she studied art at the Escuela Nacional de Pintura, Escultura y Grabado "La Esmeralda", where she met and became friends with Frida Kahlo.  She became the only female member of “Los Fridos” a group of students under Kahlo’s tutelage.  She also worked as an assistant and apprentice to Diego Rivera and David Alfaro Siqueiros, painting a number of murals of her own during her career.  The most important of this is Ronda en el tiempo at the Museo Nacional de Antropología in Mexico City.  She also created canvases and other works, with children often featured in her work and one of the first of her generation to work with ecological themes in a series of works begun in 1979.
