The invention of the typewriter is primarily credited to Christopher Latham Sholes, an American inventor. Along with Samuel W. Soule and Carlos Glidden, Sholes developed the first practical typewriter known as the Sholes and Glidden typewriter (also called the Remington No. 1), patented in 1868. Sholes also introduced the QWERTY keyboard layout that remains the standard today. Although several inventors contributed to the evolution of typewriter designs over decades, Sholes' design was the first to be commercially successful and laid the foundation for modern typewriters. He sold the patent rights in 1873 to the Remington Arms Company, which began manufacturing it commercially. Other inventors like Pellegrino Turri and William Austin Burt had earlier versions or concepts, but Sholes' was the breakthrough model.
