In 1836, Connecticut-born gun manufacturer Samuel Colt (1814-62) received a U.S. patent for a revolver mechanism that enabled a gun to be fired multiple times without reloading. Colt founded a company to manufacture his revolving-cylinder pistol; however, sales were slow and the business floundered. Then in 1846, with the Mexican War (1846-48) under way, the U.S. government ordered 1,000 Colt revolvers. In 1855, Colt opened what was the world’s largest private armament factory, in which he employed advanced manufacturing techniques such as interchangeable parts and an organized production line. By 1856, the company could produce 150 weapons per day. Colt was also an effective promoter, and by the start of the U.S. Civil War (1861-65) he had made the Colt revolver perhaps the world’s best-known firearm. He died a wealthy man in 1862; the company he founded remains in business today.
