Who invented the alarm clock ?
The earliest alarm clock I found reference to is a German iron wall clock with a bronze bell, probably made in Nuremberg in the 15th century. This clock is 19 inches tall and of open framework construction. It needed to hang high on the wall to make room for the driving weight to fall. Other alarm clocks from the 1500's are in existence.
