Abstract
It is well known that Eugene Freyssinet was the inventor of prestressed concrete. However, it is not as well known that he was a skilled craftsman and a prolific bridge builder, qualities that prepared him to invent prestressed concrete. After graduating in 1905, Freyssinet built a number of concrete arch bridges, each of which successively broke his own world record for span length. This enabled him to develop an appreciation for creep of concrete, and encouraged him to develop high quality concrete and high strength steel that were necessary for the invention of prestressed concrete in 1928. His spectacular rescue of the Le Havre Maritime Station in 1934 was the first practical application of his prestressing devices and instantly earned him a worldwide reputation. One of the more profound contributions of Freyssinet is the invention of precast segmental construction, which started with his structures of the Luzancy Bridge lineage in the 1940s, and to this day allows concrete bridges to remain competitive with steel bridges. This paper commemorates the 50th anniversary of his passing in 1962 by describing the journey taken to create an "entirely new material" that led to a "revolution in the art of building".
