America Had No Alarm Clocks — So How Did Factory Workers Wake Up on Time?

Before the alarm clock, waking up on time was a job — literally. In mill towns across America, factory whistles blew at 5 AM and a whole profession of "knocker-uppers" walked the streets at dawn, tapping bedroom windows with long poles so workers would not lose a day's pay. Then came the wind-up clock — a luxury at first, then the machine that put time discipline on every nightstand. This is the forgotten story of how America learned to wake up. In this documentary: Mary Smith, London's most famous knocker-upper; the 5 AM factory whistle and how mill owners controlled workers' time; the first mechanical alarm clocks — and why only the rich owned one; Seth Thomas and the wind-up clock that conquered America; Big Ben and the birth of radio time signals; segmented sleep, the punch clock, and the end of the knocker-upper.
