Samuel Colt (/koʊlt/; July 19, 1814 – January 10, 1862) was an American inventor, industrialist, businessman, and hunter. He initiated Colt's Patent Fire-Arms Manufacturing Company (now Colt's Manufacturing Company) and made the mass production of revolvers viable commercially.

Colt's first two business ventures were producing firearms in Paterson, New Jersey and making underwater mines; both ended in disappointment. But his business affairs improved rapidly after 1847, when the Texas Rangers ordered 1,000 revolvers during the American war with Mexico. Later, his firearms were used widely during the settling of the western frontier. Colt died during 1862 as one of the wealthiest men in America.

Colt's manufacturing methods were sophisticated for the beginning of the Industrial Revolution. His use of interchangeable parts helped him become one of the first to use the assembly line efficiently. Moreover, his innovative use of art, celebrity endorsements, and corporate gifts to promote his wares made him a pioneer of advertising, product placement, and mass marketing.
