Why Q W E R T Y?

At the beginning, this article is not mine, it is quoted from Embedded Art – Project Group, it is a great page on the social network Facebook, the page present awesome technical information and jokes about technology, so we can call it “Technical Sarcasm Society” 😉  I have just added this article because it is so important and I am completely sure you asked yourselves about it before as I am.  So let us begin:

Christopher Sholes and his typewriter

Why is the keyboard layout Q-W-E-R-T-Y and not simply A-B-C-D-F? Why were computer keyboards designed in the current format not in a alphabetical order. Is there any specific reason or it’s just some random convention we are following? It hasn’t been done randomly or just for fun, it has a very distinct and purposeful reason behind it. The current format of the keyboard was devised long back in 1870’s by a gentleman named Christopher Sholes for the then typewriter.

Though, it definitely was not the first format to come up, it didn’t take much time to switch to this one.

Starting with lexicographic order i.e. A-B-C-D-E-F, after various trials and errors and taking hundreds of cases, Christopher Sholes gradually reached the Q-W-E-R-T-Y. It was really well received (evident from the fact that we still use it).

When the typewriter was invented, it used a metal bar to hold the character alphabets and the other end of the bar was attached to a linkage carrying a carriage with the coated ink.

When a key was struck, it would emboss its character on the paper placed beneath the carriage. However, when an operator learned to type at a great speed, a certain flaw was noticed.

When two letters were struck in quick succession, the bars of the typewriter would entangle and get jammed.

Christopher Sholes found a way out. He proposed that the letters of frequently used letter pairs should be in different rows.
For example, ‘C-H’, ‘S-T’, ’T-H’, ‘W-H’ and more.

He also formulated that to speed up the typing process, there has to be a regular alternation between two hands. So observing thousands of words, he placed the letters in way that most words would make use of both hands.

He also observed that almost every word in the dictionary carries a vowel.

According to him, the most frequently used vowel was ‘A’ and the most frequently used letter (non-vowel) was ‘S’. So he placed ‘A’ and ‘S’ together and chose to keep less common letters like ‘Q’, ‘W’, ‘Z’, ‘X’, ‘C’ around these.

This was complemented by placing fairly common letters like ‘M’, ‘N’, ‘L’, ‘K’, ‘O’, ‘P’ at right extremes to create a perfect alternation between both the hands.

All these factors tested with thousands of trials gave us the format that we still use and perhaps would be using till eternity.
