Keyboard history

The Invention of the Typewriter

The typewriter was invented in the late 1800s by Christopher Sholes, a newspaper editor and printer. He developed the first practical typewriter in 1867, which used a lever-operated printing mechanism. This early model was crude and cumbersome, but it laid the foundation for the modern keyboard.

The Evolution of the Keyboard

Over the years, the keyboard underwent several changes and improvements. The first significant change came in the 1890s, when the QWERTY layout was introduced. This layout was designed to slow down the typist in order to prevent the keys from jamming together as the hammers inside the machine struck the ink ribbon to print the characters on the page.

In the early 1900s, the first electric typewriter was developed, which used an electric motor to strike the ink ribbon instead of a mechanical lever. This marked the beginning of the modern keyboard as we know it today.

The Advent of Computer Keyboards

With the advent of computers in the 1970s, the keyboard underwent another significant change. The first computer keyboards were simply adapted versions of the typewriter keyboard, but they soon evolved to include additional keys for controlling the computer. The first IBM PC, introduced in 1981, featured a keyboard with 101 keys, including a numeric keypad and function keys.

Today’s computer keyboards are available in a variety of layouts and styles, from traditional QWERTY layouts to ergonomic designs that reduce repetitive strain injuries. Many also include multimedia keys for controlling music and video playback, as well as special keys for gaming.
