However “er”, the fourth most common and “re”, the sixth most common letter pairing in the English language begins to break down this theory as they turn out to be the most used key combinations, surpassing “th”. If this theory was correct, the QWERTY keyboard system should create the maximum separation of the common letter pairings. The theory presents that Sholes redesigned the type bar so as to separate the most common sequences of letters: “th”, “he” and others from causing a jam.īigram Frequency usage of letter pairs in the english language. There was a higher possibility for the keys to become jammed if the sequence was not perfectly timed. The striker lockup came when a typist quickly typed a succession of letters on the same type bars and the strikers were adjacent to each other. The Remington QWERTY type bar connecting the keys and the letter plate. There were just two rows of type bars in Sholes design. It is important to differentiate between the typewriter’s keyboard rows and the type bars. The keys were actuated by the type bar connecting the keys and the letter plate, which formed a circle beneath the paper feed system.

How did Sholes choose to move from an almost sequential alphabetical logical order to QWERTY keyboard layout? The most popular theory posits that the inventors designed the QWERTY keyboard system to prevent the mechanical lock up of the strikers due to the close succession of adjacent often used keys that were high on the Bigram Frequency of usage. The Sholes 28 key piano style keyboard-like typewriter. But it would be his next versions that had a close version of today’s QWERTY keyboard layout. According to typewritten letters and patents of Sholes, the keyboard consisted of four rows, nearly in alphabetical order, but the “u” was next to “o”. By April, 1870 Matthias Schwalbach helped Sholes design a new typewriter with 38 keys, which consisted of capitals, numerals 2 to 9, hyphen, comma, period, and question mark. In November, 1868 Christopher Latham Sholes and his colleagues, Carlos Glidden, Samuel Willard Soulé, and James Densmore, in Milwaukee shipped out their first 28 key piano style keyboard-like typewriter to Porter’s Telegraph College in Chicago, primarily to transcribe telegraph messages. But why the QWERTY standard and not sequential alphabetical or any of the other keyboard layouts being developed by competing typewriter manufactures? Although the typewriter has a history that predates the QWERTY layout, it was a confluence of elements that gave rise to Remington winning the early typewriter standard. The rise of the industrial age to the office age in the United States closely aligns with the rise of the typewriter. Like many things in history, the QWERTY layout had fundamental contributing elements that became obscured across the span of time. This idea of the typewriter predates the office use that ultimately made it a standard business machine. The typewriter was heralded as a new way to write with greater speed, fluency and readability. The three primary confluences that motivated the QWERTY layout and the primary reasons are surprising. It was almost the QWE.TY keyboard layout.
