what was the reason behind the invention?
In earlier design pressing adjoining keys in quick succession would cause their typebars to collide and jam the machine so to mitigate this problem, keys were reordered using analysis of letter frequency and trial and error

when was the sholes and glidden typewriter invented July 1, 1874 who invented it? Christopher Latham Sholes could you tell me some details about its design? It had escapement (a mechanism governing carriage movement) adapted from clockwork, keys adapted from telegraph machines and type hammers adapted from the piano anything special about its keypad? The QWERTY keyboard was invented during the course of the typewriter's development

Gravity would then return the typebar to its initial position. The implication of this design, however, was that pressing adjoining keys in quick succession would cause their typebars to collide and jam the machine. To mitigate this problem, keys were reordered using analysis of letter frequency and trial and error. Densmore asked his son-in-law, a Pennsylvania school superintendent, what letters and combinations of letters appeared most often in the English language. Typebars corresponding to letters in commonly occurring alphabetical pairs, such as S and T, were placed on opposite sides on the ring. The keyboard ultimately presented to Remington was arranged as follows: After it purchased the device, Remington made several adjustments—including switching the period and "R" keys—which created a keyboard with what is essentially the modern QWERTY layout.
