Here is a verbal and pictorial illustration of the credo that has guided one of the world's most distinguished architects throughout his career. "Architecture is, and must be, a synthesis of technology and art."

Using nearly 200 drawings and photographs, including plans, interesting details, various stages of construction, and both interior and exterior views of some of his major works, Mr. Nervi shows how his philosophy is put into practice. Referring to most of his important projects, he discusses solutions to various functional and construction requirements where he used precast and cast-in-place concrete, emphasizing the richness of this material. Mr. Nervi stresses the advantages of reinforced concrete, which, he says, allows greater flexibility and makes it easier to satisfy his triple demand of economy, technical correctness, and aesthetic satisfaction.

In predicting the future of architecture he stresses the necessity of architectural solutions that are functionally and technically sound. His final remarks concern his ideas about the proper course of study for architecture students, training that will produce architects with a "far greater technical sense than in the past, a technical sense which results in a constant search for economic efficiency."

Born in Sondrio, Italy, in 1891, Pier Luigi Nervi was a pioneer in the engineering and architecture of reinforced concrete. His buildings showed how the use of reinforced concrete expanded the possibilities of form and structure. His methods, meanwhile, ingrained his structures with patterns that came directly out of his economical, manual construction processes. The results were buildings that matched awe-inspiring spans with surprisingly human scale.

Beauty's Rigor offers a comprehensive overview of Nervi's long career. Drawing on the Nervi archives and a wealth of photographs and architectural drawings, Thomas Leslie explores celebrated buildings like Palazetto dello Sport built for the 1960 Rome Olympics, St. Mary's Cathedral in San Francisco, and the UNESCO headquarters in Paris. He also sheds new light on unbuilt projects such as the Pavilion of Italian Civilization for the Universal Exposition of Rome E42. What emerges is the first complete account of Nervi's contributions to modern architecture and his essential role in a revolution that realized concrete's potential to match grace with strength.
