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.
