In 1714, Mill, an English engineer, obtained a patent for a machine for transcribing letters. In 1808, the first functional typewriter was made by Pellegrino Turri. In 1829, the first American patent for a primitive typewriter was given to William Burt. Malling-Hansen's invention of the writing ball in 1870 was another successful version of the typewriter.
