The Qwerty Keyboard

Many legends surround Sholes' development of the keyboard. It is not laid out based on the frequency of use of certain letters, nor are the most used letters placed under the strongest fingers. The most frequently quoted story, that it is based on the arrangement of the letters in the printers' type-case-in the days when every printed page was set individual letter and symbol by hand-is false. Most likely Sholes changed the order of the keys as he created prototype after prototype of his machine, trying to eliminate the most frequently occurring jams, when two nearby keys would meet. The layout kept frequently combined letters separated mechanically, which limited the number of possible collisions between type bars. It probably also slowed the rate a good typist could reach, further eliminating possible jams.
