Italian engineer and architect (Sondrio 1891 - Rome 1979). Graduated in engineering (1913) in Bologna, he worked for ten years in a firm that specialized in reinforced concrete constructions, acquiring an experience that would be fundamental for his further activity. Possessor of an exceptional technical and scientific preparation (among other things it was him who invented Ferro-cement in 1940), in his work he was always based upon the assumption that there is no contrast between the static-constructive solution to an architectonic problem and its aesthetic result. Already in Florence 's Stadium (1930-32) and in the project (1939-41) for airplane hangars composed by elements in reinforced concrete; in the system of right angle framework, adopted until that time in reinforced concrete buildings, he began to place instead constructive curved elements, intermittently, that were as innovative as they were bold. Equally stunning were the results obtained by Nervi in the Salone dell'Esposizione di Torino (1948-49), using prefabricated reinforced concrete parts he managed to put together a barrel vault that covers a 75 meter span and is in some points only 5 centimeters thick. I the same measure in all of his most recent production (Palazzetto dello Sport in Rome, 1958, in collaboration with A. Vitellozzi; Palazzo dello sport in Rome, 1959-60 (iter 2) , in collaboration with M. Piacentini; Palazzo dell'UNESCO in Paris, 1953-58, in collaboration with M. Breuer and B. H. Zehrfus; Palazzo del Lavoro in Turin, still not completed), in the same moment in which he was accomplishing new constructive procedures he achieved very high stylistic results demonstrating thereof the thesis sustained by him that art and the science of construction are two aspects of one single reality. “I consider I can affirm that a good structural organism…, is the necessary condition, if not entirely sufficient, of a good architecture”. This is what the architect-engineer précised in the preface written by him to a book that depicts all of his work.
