With the help of friends' Carlos Glidden and Samuel Soule, Christopher Sholes in 1868 patented a simple device with printers type mounted to strike upward onto a flat plate holding carbon paper against stationary. The idea of type striking against paper to create an image was the revolutionary concept behind Sholes' "Type-Writer."
