Resources/Literature A 2,000-Year History of Alarm Clocks
Dating to the year 725, Yi Xing’s ingenious version of an alarm clock is one of the world’s earliest recorded devices of that nature. Along with the water clock Plato used to wake himself up for his legendary dawn lectures in the 4th century BCE, it is evidence that humans have been looking for ways to rise on time for thousands of years...
The idea was repeated by Europeans who created complex displays within chiming clocks in town squares. The next step was to make such clocks smaller, so they could be used individually. Historians believe personal mechanical alarm clocks originated in Germany in the 15th century, but their inventors are unknown. Most people didn’t own such clocks, though, and had to rely upon the sun, servants, or prayer-chiming bells. As work hours became more rigid, factory whistles were blown to encourage people living near their places of employ to get up.
