Florent-Jean de Vallière

Jean-Florent de Vallière (7 September 1667 – 7 January 1759) 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.

Vallière was a member of the Académie de Marine. After his death, his seat went to Chabert-Cogolin.

Through the Royal Ordonnance of 7 October 1732, 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.
