Peter Henlein (or Heinlein or Henle or Hele) (1479/1480 – August 1542), a locksmith and watchmaker from Nuremberg, is often considered the inventor of the portable timekeeper, making him the inventor of the watch, but this claim is disputed. His small, drum-shaped Taschenuhr, a portable watch which he built during his asylum from 1504 to 1508, could run for forty hours before it needed rewinding.
