The QWERTY keyboard was designed to prevent jams on a keyboard. The early typewriters used arms to impress a letter on paper. If neighbouring keys were used in rapid sucession, then the arms were likely to jam, which was a serious issue. The keyboard was designed to prevent commonly used key combinations from being next to each other. It is widely believed that the keyboard was designed to slow down typists, which is not true.
