History of KeyboardThe First Beginnings of the Computer Keyboard:

The history of computer keyboards begins indirectly with world’s first ever commercially successful typing machine, which was invented by a man called Chistopher Latham Scholes during 1873.

In the first design, the keys on the keyboard were arranged in alphabetically order. However there was a fundamental problem that soon arose with this design.

Scholes thought for a long time for ways of overcoming the problem, making alterations to the design of the keys, but nothing seemed to stop them from getting stuck. Finally though the solution came to him. If he coudn’t stop the keyboard from jamming, then he would simply act to slow the person typing down. To do this, Scholes hit upon the idea of placing the most often used keys away from each other,as far as possible. Then The modern keyboard known as QWERT was born.
