Rufino Tamayo (1899-1991) is best known as a painter who was a contemporary of Diego Rivera and Jose Clemente Orozco. In the latter part of his career, he turned to sculpture. Tamayo designed and oversaw the fabrication of Conquest of Space in 1983 when he was 84 years old. It was the first sculpture by this internationally-acclaimed artist to be permanently placed outside of Mexico. The 32-foot-tall steel sculpture consists of triangular forms alternately painted red and blue.
