Julian Hatcher

From Wikipedia, the free encyclopedia

Julian Sommerville Hatcher (June 26, 1888 – December 4, 1963), was a noted firearms expert and author of the early twentieth century. He is credited with several technical books and articles relating to military firearms, ballistics, and autoloading weapons. His premier works are Hatcher's Notebook and Book of the Garand. He was also a pioneer in the forensic identification of firearms and their ammunition. Hatcher retired from the United States Army as a Major General.

Hatcher was born in Hayfield, Virginia and graduated with honors from Annapolis in 1909. He married Eleanor Dashiell and together, they had three children. Chief of the Small Arms Division in the Ordnance Department and the Assistant Commandant of the Ordnance School before and at the beginning of World War II, he worked closely with Springfield Armory as an engineering trouble-shooter in resolving early production issues associated with the early iterations of the M1 Garand Rifle.

In 1916, the Hotchkiss M1909 Benet-Mercie machine gun was in general use with the U.S. Army and was seeing action during the Punitive Expedition against the bandit Pancho Villa. Reports of its use in Mexico indicated the gun was not functioning properly. Investigation revealed that the chief problems were the 30-round metallic feed strips used in the gun and inexperienced gunners. It was Lieutenant Hatcher who was sent to the border to solve the problems. He found that none of the soldiers had been taught the proper use of the weapon. He set up the Army's first machine gun school and was soon turning out trained crews. Soon, the Benet-Mercie proved to be an effective weapon.

Hatcher was later instrumental in developing a solution to the vexing problem of brittle metal in early M1903 receivers built by Springfield and Rock Island Arsenals. His solution was to drill a hole in the receiver adjacent to breech. Dubbed the "Hatcher Hole", the modification was typically added to receivers at overhaul.
