The QWERTY keyboard was invented in 1873 by American inventor and newspaper publisher Christopher Latham Sholes, who developed a number of devices to make his businesses more efficient. The QWERTY keyboard layout was created for the Sholes and Glidden typewriter and sold to E. Remington and Sons in 1873, becoming popular with the success of the Remington No. 2 of 1878, and remains in ubiquitous use today [1][2].
The reason for the QWERTY keyboard's invention is disputed, but one theory is that the inventors designed the QWERTY keyboard system to prevent the mechanical lock-up of the strikers due to the close succession of adjacent often-used letters [3]. Another theory suggests that the QWERTY keyboard was designed to slow typists down and prevent jamming of the mechanical keys
