Invention of Keyboard♒

Invention of the first keyboard

There were different types of invention, as well as the typewriter, keypunches, and teleprinters that helped to develop the computer keyboard. In the 1700s, the first writing devices were designed, and Henry Mills filed patented in London, England, in 1714.

Invention of the typewriter

The different typing and writing devices were created around the world in the late 1700s and the beginning of the 1800s. Although, in 1868, Christopher Sholes developed and patented the first practical typewriter and the word Type-Writer that is considered to be the first typewriter.

Additionally, the QWERTY keyboard design was introduced by the Type-Writer, which is still

mainly used on US keyboards today. Samuel W. Soule, Christopher Sholes, and Carlos Glidden created a Type-Writer that picture shown in the below:

In 1878, the first keyboard with a Shift key was invented that had one Shift key on the left side of the keyboard. The Underwood typewriter is considered the first successful modern typewriter, till 1939, five million of its typewriters were sold. The first Underwood typewriter was invented by Franz Xaver Wagner, and on 27 April 1893, he filed to patent the typewriter U.S. patent 523,698. The biggest improvement of Underwood typewriter, it was capable of seeing the writing it was typed. Later in 1895, Franz Xaver Wagner created the Underwood company with the help of John Underwood and introduced its first typewriter in 1896.

Before introducing the IBM Selectric typewriter by IBM on 27 July 1961, typewriters from all manufacturers began to become more alike. Unlike other typewriters, the IBM Selectric typewriter used a typeball, which containing characters that would strike an ink ribbon. Furthermore, this typewriter was sold more than 13 million until 1986.

The invention of keypunch, the telegraph, and teleprinter

Joseph Marie Jacquard developed the Jacquard Loom in the late 1700s, which was expanded by Herman Hollerith with his keypunch inventions in the late 1800s and the beginning of the 1900s.

In 1832, Pavel Schilling invented the first electrical telegraph and to send Morse code messages over a line, allowing for a single key to be used. Later in 1846, a printing telegraph was patented by Royal Earl House, which used 28 piano-style keys. The keys made it easy to send messages by representing each letter in the alphabet. In 1874, the Baudot code was invented by Emile Baudot; later, it was extended by Donald Murray (inventor of thetelegraphic typewriter). Charles Krum helped invent the teleprinter by working to continue on Frank Pearne that was developed from 1902 to 1918. In August 1907, he filed patent U.S. patent 862,402. Also, he filed patent 888,335 in May 1908, and patent 1,286,351 in May 1910.

Early computers with keyboards

After many years, in 1964, the introduction of Multics and video display terminals (VDTs), which enabled users to see typing on the screen what they are typing.

The DataPoint 3300 began to ship by the Computer Terminal Corporation in 1969. It was the first computer terminal designed to replace the teleprinter. Some other versions of this terminal were also introduced as well as HP 2600A, DEC, and VT06. The DataPoint 3300 was a terminal that was able to move the cursor using arrow keys, and it used a screen display to show typed text. Also, it had the ability to clear all text on the screen.

At the beginning of the 1970s, keyboards began to use what we use today. Those keyboards were heavy mechanical or reconstructed electric typewriters from companies such as IBM. Apple, Radio Shack, and Commodore introduced their computers in the late 1970s that come included keyboards. Later, IBM PC and the Model F keyboard introduced by IBM in August 1981.

The Model M keyboard was introduced by IBM in 1986, which contained function keys like today's keyboards have across the top of the keyboard. The Model M is still considered a high keyboard as it has a standard US layout with 101-key, which is used for full-sized keyboards today. It is also designed for windows keyboards that have 104-key with the Menu keys and windows keys.

Since IBM introduced the Model M keyboard, many changes have been in the keyboard that is in use today. A membrane helps to manufacturer computer keyboards easily and reduce manufacturing costs. Furthermore, the membrane keyboard makes the keyboard lighter, thinner, and quieter as compared to the first mechanical keyboards.
