Sébastien Le Prestre de Vauban, French general and engineer (b. 1633)
Sébastien Le Prestre de Vauban, Seigneur de Vauban, later Marquis de Vauban (1 May 1633 – 30 March 1707), commonly referred to as Vauban (French: [vobɑ̃]), was a French military engineer who worked under Louis XIV. He is generally considered the greatest engineer of his time, and one of the most important in Western military history.
His principles for fortifications were widely used for nearly 100 years, while aspects of his offensive tactics remained in use until the mid-twentieth century. He viewed civilian infrastructure as closely connected to military effectiveness and worked on many of France's major ports, as well as projects like the Canal de la Bruche, which remain in use today. He founded the Corps royal des ingénieurs militaires, whose curriculum was based on his publications on engineering design, strategy and training.
His economic tract, La Dîme royale, used statistics in support of his arguments, making it a precursor of modern economics. Later destroyed by Royal decree, it contained radical proposals for a more even distribution of the tax burden. His application of rational and scientific methods to problem-solving, whether engineering or social, anticipated an approach common in the Age of Enlightenment.
Perhaps the most enduring aspect of Vauban's legacy was his view of France as a geographical entity. His advocacy of giving up territory for a more coherent and defensible border was unusual for the period; the boundaries of the French state he proposed in the north and east have changed very little in the four centuries since.
