Karl Drais was a German inventor, who invented the Laufmaschine, also later called the velocipede, draisine or draisienne, also nicknamed the dandy horse. This incorporated the two-wheeler principle that is basic to the bicycle and motorcycle and was the beginning of mechanized personal transport. Drais also invented the earliest typewriter with a keyboard in 1821, later developed into an early stenograph machine, a meat grinder, and a wood-saving cooker using a hay chest.
