Samuel Colt was an American inventor born in 1814 who developed the first successful revolver. Before Colt's invention, guns could only fire one shot before needing to be reloaded. Colt received patents for his revolver design in both England and America in 1836. His revolvers helped the United States military succeed during the Texas Revolution and Mexican-American War. Colt's revolver became the iconic handgun design, providing multiple shots from a cylinder in a simple and powerful design that was well-suited for frontier defense and military use.
