Count Antoine Hector Thésée Treuille de Beaulieu (7 May 1809 – 24 July 1885) was a French General of the 19th century, who developed the concept of rifled guns in the French Army.[1] He studied the subject of rifling between 1840, particularly in the famous Manufacture d'armes de Châtellerault, and 1852.[2] Following a request by Napoleon III in 1854 to develop such a weapon, the de Beaulieu system was adopted by the French Army. It consisted in cutting six grooves inside the bore of a muzzle-loading cannon, and to use shells equipped with six lugs which would engage the grooves.[3] This development was paralleled by that of the Armstrong gun in Great Britain (adopted in 1858 by the British Army).[3]

About the same time he developed a pinfire falling-block breech-loading carbine (mousqueton) for the Cent-gardes Squadron which was a bit ahead of its time in using a metallic cartridge and is very unusual (for a single-shot weapon) in that it fires from an open bolt.[4]
These developments led to the introduction of the La Hitte system in 1858, a fully integrated system of muzzle-loading rifled guns. The Beaulieu 4-pounder rifled field-gun was adopted by the French Army in 1858, where it replaced the canon-obusier de 12, a smoothbore cannon using shells which was much less accurate and shorter-ranged.[5]
The Beaulieu rifled artillery was first used in Algeria, and then in the Franco-Austrian War in Italy in 1859.[6]
In 1842 he invented a prototype of the modern muzzle brake and had it tested in 1862.[7]
