Samuel Colt was an American inventor, industrialist, and businessman who established Colt's Patent Fire-Arms Manufacturing Company and made the mass production of revolvers commercially viable.

Colt's Manufacturing Company, LLC is an American firearms manufacturer, founded in 1855 by Samuel Colt and now a subsidiary of Czech holding company Colt CZ Group. It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836. Colt is known for the engineering, production, and marketing of firearms, most especially between the 1850s and World War I, when it was a dominating force in its industry and a seminal influence on manufacturing technology. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from single-shot pistols. Although Samuel Colt did not invent the revolver concept, his designs resulted in the first very successful model.
