Qwerty

In 1866, Christopher Sholes invented the first practical modern typewriter. On his first model, the letters on the keyboard were arranged in alphabetical order and this caused problems because the keys jammed easily when the typist worked quickly. Sholes with assistance from James Desmore rearranged the typewriter keyboard by splitting keys for letters commonly used to prevent them from sticking to each other. This arrangement became today's standard "Qwerty" keyboard.
