Typewriter: Christopher Latham Sholes received a patent for an invention he called the "Type-Writer."

Christopher Latham Sholes (February 14, 1819 February 17, 1890) was an American inventor who invented the QWERTY keyboard, and, along with Samuel W. Soule, Carlos Glidden and John Pratt, has been contended to be one of the inventors of the first typewriter in the United States. He was also a newspaper publisher and Wisconsin politician. In his time, Sholes went by the names C. Latham Sholes, Latham Sholes, or C. L. Sholes, but never "Christopher Sholes" or "Christopher L. Sholes".

A typewriter is a mechanical or electromechanical machine for typing characters. Typically, a typewriter has an array of keys, and each one causes a different single character to be produced on paper by striking an inked ribbon selectively against the paper with a type element. At the end of the nineteenth century, the term 'typewriter' was also applied to a person who used such a device.The first commercial typewriters were introduced in 1874, but did not become common in offices until after the mid-1880s. The typewriter quickly became an indispensable tool for practically all writing other than personal handwritten correspondence. It was widely used by professional writers, in offices, business correspondence in private homes, and by students preparing written assignments.

Typewriters were a standard fixture in most offices up to the 1980s. Thereafter, they began to be largely supplanted by personal computers running word processing software. Nevertheless, typewriters remain common in some parts of the world. In many Indian cities and towns, for example, typewriters are still used, especially in roadside and legal offices due to a lack of continuous, reliable electricity. The QWERTY keyboard layout, developed for typewriters in the 1870s, remains the standard for computer keyboards, although the origins of this layout remain in dispute, whether it was developed for mechanical reasons or to suit the operator, particularly Morse code operators Notable typewriter manufacturers included E. Remington and Sons, IBM, Godrej, Imperial Typewriter Company, Oliver Typewriter Company, Olivetti, Royal Typewriter Company, Smith Corona, Underwood Typewriter Company, Adler Typewriter Company and Olympia-Werke.
