Félix Candela was a Spanish architect and engineer known for his innovative work with thin-shell structures. Born in 1910, he became famous for designing elegant, lightweight buildings that used minimal materials while maintaining strength and beauty. His most notable creations include the Palacio de los Deportes in Mexico City and the Church of the Virgin of the Miracle in the same city, showcasing his mastery of concrete. Candela's designs often featured hyperbolic paraboloids and other geometric shapes, which allowed for large open spaces without the need for heavy support. His pioneering techniques have influenced modern architecture and engineering, making him a key figure in the field.
