Exhibit: “The Art of Structure,” Carnegie Museum of Art

Engineers may traffic in science and numbers, but the best ones also bring an aesthetic eye to their work, as The Art of Structure, now on display at Pittsburgh’s Carnegie Museum of Art, demonstrates. The exhibit comprises two shows: “The Art of Structural Design: A Swiss Legacy,” which focuses on the projects of four 20th century Swiss engineers, including Christian Menn’s Sunniberg Bridge; and “Félix Candela: Engineer, Builder, Structural Artist,” which posits that the Spanish architect’s distinctive, thin-shell concrete designs are more than just elegant engineering.
