U.S. firearms manufacturer and inventor.

In 1800 his family settled near Utica, N.Y., where his father built a smithy and forge powered by a waterwheel. In 1816 Remington constructed a flintlock rifle at the forge; its accuracy led neighbours to order similar guns. Soon, manufacture of sporting guns and rifle barrels became the main business of the forge.

In 1828 Remington built a large factory beside the Erie Canal at the present site of Ilion. He and his son Philo pioneered many improvements in arms manufacture, including the reflection method of straightening gun barrels, a lathe for cutting gunstocks, and the first successful cast-steel, drilled rifle barrel manufactured in the United States.

In 1847 Remington supplied the U.S. Navy with its first breech-loading rifle (Jenks carbine). The company he founded, the Remington Arms Company, supplied a large proportion of the small arms used by the U.S. government in the Civil War (1861–65) and in World Wars I and II.
