Félix Candela worked as an architect upon his arrival in Mexico until 1949 when he started to engineer many concrete structures utilizing his well-known thin-shell design. Candela did most of his work in Mexico throughout the 1950s and into the late 60s. He was responsible for more than 300 works and 900 projects in this time period. Many of his larger projects were given to him by the Mexican government, such as the Cosmic Rays Pavilion. In 1956, Mexican President Adolfo Ruiz Cortines said “Nothing could be more serious than to sit in the shade of the buildings we are about to build,” foreshadowing the many construction projects to come. Ruiz Cortines came up with a budget to enable his construction declaration to come true, requesting ₱81,200,000 (pesos) more funding than was used in 1955. Luckily for Candela, ₱20,300,000 (pesos) of this funding was to go towards public works. Candela also benefited from the budget implemented by Ruiz Cortines in the area of education. Candela became a professor in Mexico, which is what he did for the remainder of his career. Felix moved to the United States and taught at University of Illinois at Chicago from 1971-1978.
