French engineer and pioneer of reinforced-concrete construction. He designed several bridges, including Plougastel (1924–30), five bridges over the Marne (1947–51), and the Saint-Michel Bridge, Toulouse (1959–62). During the 1914–18 war he designed industrial buildings with reinforced-concrete roofs, followed by two huge parabolic-arched airship-hangars at Orly (1916–24). He developed prestressed concrete (which he patented in 1928), and published much on his ideas and methods from 1921 until 1954, including Une Révolution dans les techniques du béton (A Revolution in the Techniques of Concrete—1936).
