Never. The alarm clock was invented by Levi Hutchins of Concord, New Hampshire, in 1787.
The history of the first alarm clock dates back the Greek philosopher Plato, around 428-348 BC. It was a water clock with an alarm signal similar to a water organ.
Levi Hutchins of Concord, New Hampshire, invented an alarm clock in 1787. His alarm clock, however, rang at only one time-4 a.m. He invented this device so that he would never sleep past his usual waking time. He never patented or manufactured it. The first modern alarm clock was made by Antoine Redier (1817-1892) in 1847. It was a mechanical device; the electric alarm clock was not invented until around 1890. The earliest mechanical clock was made in 725 c.e. in China by Yi Xing and Liang Lingzan.
The first radio alarm clock was invented by James F. Reynolds.
