It makes no sense. It is awkward, inefficient and confusing. We've been saying that for 124 years. But there it remains. Those keys made their first appearance on a rickety, clumsy device marketed as the "Type-Writer" in 1872. Today the keyboard is a universal fixture even on the most advanced, sophisticated computers and word processors electronic technology can produce.
.
How could we get stuck with something so bad?
.
In this case, the answer lies in the old proverb about the early bird catching the worm. As far as the typewriter keyboard is concerned, being first was the whole ball game.




1878 Typewriter Patent Drawing, featuring the QWERTY Keyboard. Years after its introduction, it was considered important enough to include in a patent.
.
The name "QWERTY" for our typewriter keyboard comes from the first six letters in the top alphabet row (the one just below the numbers). It is also called the "Universal" keyboard for rather obvious reasons. It was the work of inventor C. L. Sholes, who put together the prototypes of the first commercial typewriter in a Milwaukee machine shop back in the 1860's.
.
For years, popular writers have accused Sholes of deliberately arranging his keyboard to slow down fast typists who would otherwise jam up his sluggish machine. In fact, his motives were just the opposite.
.
When Sholes built his first model in 1868, the keys were arranged alphabetically in two rows. At the time, Milwaukee was a backwoods town. The crude machine shop tools available there could hardly produce a finely-honed instrument that worked with precision. Yes, the first typewriter was sluggish. Yes, it did clash and jam when someone tried to type with it. But Sholes was able to figure out a way around the problem simply by rearranging the letters. Looking inside his early machine, we can see how he did it.
.
The first typewriter had its letters on the end of rods called "typebars." The typebars hung in a circle. The roller which held the paper sat over this circle, and when a key was pressed, a typebar would swing up to hit the paper from underneath. If two typebars were near each other in the circle, they would tend to clash into each other when typed in succession. So, Sholes figured he had to take the most common letter pairs such as "TH" and make sure their typebars hung at safe distances.
.
He did this using a study of letter-pair frequency prepared by educator Amos Densmore, brother of James Densmore, who was Sholes' chief financial backer. The QWERTY keyboard itself was determined by the existing mechanical linkages of the typebars inside the machine to the keys on the outside. Sholes' solution did not eliminate the problem completely, but it was greatly reduced.
.
The keyboard arrangement was considered important enough to be included on Sholes' patent granted in 1878 (see drawing), some years after the machine was into production. QWERTY's effect, by reducing those annoying clashes, was to speed up typing rather than slow it down.
.
Sholes and Densmore went to Remington, the arms manufacturer, to have their machines mass-produced. In 1874, the first Type-Writer appeared on the market. No contemporary account complains about the illogical keyboard. In fact, few contemporary accounts even mention the machine at all. At its debut, it was largely ignored.
.
Sales of the typewriter did not take off until after Remington's second model was introduced in 1878, offering the only major modification to the keyboard as we know it today.
.
The first machines typed only capital letters. The new Remington No. 2 offered both upper and lower case by adding the familiar shift key. It is called a shift because it actually caused the carriage to shift in position for printing either of two letters on each typebar. Modern electronic machines no longer shift mechanically when the shift key is pressed, but its name remains the same.
.
In the decades following the original Remington, many alternative keyboards came and went. Then, in 1932, with funds from the Carnegie Foundation, Professor August Dvorak, of Washington State University, set out to develop the ultimate typewriter keyboard once and for all.
.
Dvorak went beyond Blickensderfer in arranging his letters according to frequency. Dvorak's home row uses all five vowels and the five most common consonants: AOEUIDHTNS. With the vowels on one side and consonants on the other, a rough typing rhythm would be established as each hand would tend to alternate.




.
With the Dvorak keyboard, a typist can type about 400 of the English language's most common words without ever leaving the home row. The comparable figure on QWERTY is 100. The home row letters on Dvorak do a total of 70% of the work. On QWERTY they do only 32%.
.
The Dvorak keyboard sounds very good. However, a keyboard need to do more than just "sound" good, and unfortunately, Dvorak has failed to prove itself superior to QWERTY. It appears that many of the studies used to test the effectiveness of Dvorak were flawed. Many were conducted by the good professor himself, creating a conflict of interest question, since he had a financial interest in the venture. A U.S. General Services Administration study of 1953 appears to have been more objective. It found that it really didn't matter what keyboard you used. Good typists type fast, bad typists don't.
.
It's not surprising, then, that Dvorak has failed to take hold. No one wants to take the time and trouble to learn a new keyboard, especially if it isn't convincingly superior to the old. A few computer programs and special-order daisy wheels are available to transform modern typewriters or word processors to the Dvorak keyboard, but the demand for these products is small. After all, expert typists can can do nearly 100 words a minute with QWERTY . Word processors increase that speed significantly. The gains that Dvorak claims to offer aren't really needed.

Interesting that the letters included in the "home row" where you rest your fingers were those that were least used in order to prevent "clashes" between typewriter keys hitting the paper at the same time. So typing efficiency was slowed by spreading out the most frequently used letters (the vowels). Obviously, with computers this is no longer a problem and alternative keyboard designs have been proposed, but just as with the metric system here in the USofA no one wants to bite the bullet and make the switch, even though it makes sense..

at the top of the keyboard the letters are arranged qwerty rather than in alphabetical order as the person who designed it felt that having the most often used letters together was more efficient and the less used letters such as q p and zx and m away from the main typing area would be easier to learn.

Yeah, it's on your keyboard, funny thing about it though, it was an accident and now it's our standard. The reason for this layout is that early typewriters had a mechanical issue where the keys that were used frequently and in close proximity began sticking. This obviously made it tough to type, so in order to alleviate the problem they changed the keyboard layout...

Way to "solve" the problem, huh?

It's called that because the first 6 letters on the top line of English keyboards are q - w - e - r - t - y

look at your keyboard, first 6 letters, QWERTY
