The typewriter with this keyboard layout, the Sholes and Glidden typewriter, was released in 1874. The first design Sholes sold to Remington in 1873 was actually the QWE.TY keyboard. The first keyboard design by Christopher Latham Sholes to sway from the traditional alphabetic design was actually not the QWERTY design. Skeptics will argue that the “ER” and “RE” letter pairings are both in the top ten most common letter pairings, and the fact that they are adjacent to one another on the QWERTY design, opposes this theory.

Others debunk this saying that if this theory was actually correct, the QWERTY keyboard system should separate common letter pairings to avoid this same issue.

Typewriters with keys in alphabetical order often experienced this issue due to the close succession of frequently-used keys adjacent to one another (for example, the “S” and “T” keys). Some say that the QWERTY keyboard was originally designed to slow down typing speeds in order to prevent the mechanical lock up of the strikers. Hansen's machine was quite popular in Scandinavia and it was certainly superior to Sholes' typewriter, but it faded from popularity as the machines made by Remington and its competitors became standard office equipment in America and across the world.There is a lot of speculation that goes in to why the QWERTY keyboard was invented. In 1865, Denmark's Rasmus Malling-Hansen invented the skrivekugle, an elegant and brilliantly-engineered device in which paper was attached to a cylinder and rolled under a 'writing ball' that whirled under fifty-two densely-arranged buttons, which users pushed to select characters. The user would rotate a selection bar until it was over the desired character, then click a button to print that letter, somewhat similar to present-day novelty machines at carnivals. In 1829, William Burt of Detroit patented his 'typographer', a machine with the alphabet laid out on a dial. A few of the letters written on that machine have survived, but nothing is known about the machine itself or how it worked. In about 1808, an Italian inventor, Pellegrino Turri, built a device that allowed his blind friend to 'type' notes. In 1714, British mill worker Henry Mill received a patent for what he described as 'an artificial machine or method for the impressing or transcribing of letters singly or progressively one after another, as in writing, whereby all writing whatever may be engrossed in paper or parchment so neat and exact as not to be distinguished from print.' The details of Mill's machinery have been lost to history. Dozens of contraptions had accomplished this in different ways before Sholes began working on the problem. Sholes is usually credited as the inventor of the typewriter, but certainly, his machine was not the first device that could mechanically put letters and words onto paper. The first Remington model, marketed as the 'Sholes & Glidden Type Writer', was not a great success, but Mark Twain bought one, and later described it as a 'curiosity-breeding little joker'. Remington's engineers made quick work of the remaining mechanical problems, and the company began selling typewriters in late 1873. Remington and Sons Company (the gunmaker now known as Remington Arms Co.) and relinquished all rights to the machine. Still, Sholes grew frustrated tinkering with his machine and doubted that it could be manufactured and sold at a reasonable yet profitable price. This arrangement of letters, commonly called 'qwerty' for the first six keys in the upper left corner of the keyboard, has been the standard for typewriters ever since, and is used in modern word processors, personal computers, and other devices. The keys of Sholes' typewriter had been arranged in alphabetical order, but the mechanical bars which struck the paper consistently jammed, so he rearranged his keyboard, putting the letter-bars that had jammed most frequently farther apart. Sholes soon purchased his partners' shares in the invention, and then spent five more years trying to refine the rather cumbersome device. With help from two friends, Carlos Glidden and Samuel Soulé, he built his machine, which mimicked the appearance of typeset pages by impressing one inked character at a time onto paper. He was a printer by trade, and familiar with the tedious, time-consuming process of typesetting. The first modern typewriter was designed by Christopher Sholes in 1868.
