A native of Dieppe, Guillaume Denys (1624-1689) was ordained a priest in 1647, but his keen interest in the world of navigation led him to teach hydrography, a vocation supported by the great Colbert, who granted him a pension of 1,200 livres, enabling him to found the Dieppe School of Hydrography in 1664. The school soon welcomed around a hundred students, including future great navigators such as Cauvette and Corruble.
