Florent-Jean de Vallière

Who was Florent-Jean de Vallière?

Jean-Florent de Vallière was a French artillery officer of the 18th century. He was lieutenant-general of the King's Armies. In 1726, de Vallière became Director-General of the Battalions and Schools of the Artillery.

Through the Royal Ordonnance of October 7, 1732, de Vallière endeavoured to reorganize and standardize the King's artillery. He significantly improved the method used for founding cannons, superseding the technique developed by Jean-Jacques Keller. He thus developed the de Vallière system, which set the standard for French artillery until the advent of the Gribeauval system.
