Marquis de Vauban

1633–1707 · French · Reign of Louis XIV

Known for: History's greatest military engineer—designed 300 fortresses and conducted 53 successful sieges

Sébastien Le Prestre de Vauban was history's greatest military engineer. He designed or improved over 300 fortresses across France and conducted 53 successful sieges, reducing fortress warfare to a mathematical science. The saying 'A city defended by Vauban cannot be taken; a city besieged by Vauban cannot hold' captured his dual mastery.

He was unusual among military figures for his humanitarian concerns—he worried about civilian casualties and the welfare of common soldiers. Late in life, he wrote a treatise advocating tax reform that angered Louis XIV and led to his disgrace. He died shortly after, having been right about everything.
