Typewriter
Descripción:
 "Like many modern inventions, the typewriter wasn’t the result of a single genius, but was gradually developed by a succession of visionaries starting in the mid-1700s. But it wasn’t until the 1870s that the first really practical typewriters went on sale. In 1878, typing visionary Christopher Latham Sholes, a former journalist and customs inspector, came up with the idea of equipping a typewriter with a QWERTY keyboard, whose arrangement of letters was designed to slow typists’ fingers slightly and prevent typewriters from jamming."
