Mexican-American visual artist (b. 30 January 1895, Rincón de Velázquez, Mexico; d. 17 February 1963, Auburn, CA). Migrating to the United States in the mid 1920s in order to gain employment with the Californian rail system, Ramírez suffered a mental breakdown and was committed to Stockton State Hospital in 1931 as a catatonic schizophrenic. After moving to DeWitt State Hospital in 1948, Ramírez began to create elaborate drawings and collages. He remained institutionalized and continued to produce artworks until his death in 1963. Ramírez' work is characterized by repeating geometric patterns and trains.
