John Moses Browning (01/23/1855-11/26/1926), one of the most prolific and successful firearms designers in history, with over 126 firearms-related patents to his name. He designed more weapons still in production today than any other firearms designer of his time. Responsible for the Browning Automatic Rifle (favorite weapon of both Clyde Barrow of Bonnie & Clyde fame and Frank Hamer, the Texas Ranger who took Clyde down), the Browning M2 heavy machine gun (still on active duty with the US Army), the Browning Hi-Power automatic pistol (still in production through Fabrique National of Belgium), the Colt M1911 A1 ACP autopistol that used his slide operation (still in production by Springfield Armory, and up until a couple of years ago the Winchester Model 1894 lever-action rifle.
John M. Browning's excellence in weapons design is proven by the fact that his weapons are still in production a hundred years after they were first introduced.
