Hubert Gautier

Died 27 Sep 1737 at age 77 (born 21 Aug 1660).French engineer who authored the first book on bridge building, Traité des Ponts, in 1716. It covered bridges in masonry and timber, foundations, piers and centering, the velocity of water, and such reference tools as a dictionary of terms and a list of edicts. He had previous written a treatise of roads, published in 1693. Originarily a medical doctor, he became a naval engineer and later on general inspector of the Ponts et Chaussées. He also authored books on fortifications, the antiquities of his native town Nîmes, and a first manual for watercolor practitioners. Watercolor had also some military interest, as it was needed for mapmakers in order to impart the correct hue, and this explains why Gautier choose to write this treatice.
