Jules Dupuit was perhaps the most illustrious of the French engineer-economists. Trained at the École des Ponts et Chaussées in Paris, Dupuit had a distinguished career as a civil engineer. Starting out as chief engineer in the Sarthe region, Dupuit wrote several first-class theoretical and practical studies of road deterioration and maintenance (1837, 1842), for which he earned a Légion d'honneur in 1843. His studies on flood management (1848), drawn from his experience in the Loire, also made a big impression. Dupuit was called to Paris in 1850 and made chief engineer. It was here that he made he studies of municipal water systems and hydraulics and supervised the construction of the Paris sewer system. In 1855, he was named inspector general of the Corps des Ingénieurs and served on the Conseil des Ponts et Chaussées until his death.

Engineering questions led into his seminal contributions to economics. His 1844 articles was concerned with the find the toll that should be charged on a bridge. It was here that he introduced his curve of diminishing marginal utility and suggested that, the higher the toll, the lower
