Before the days of smartphones, loud alarm clocks, and snooze buttons, there existed an unlikely profession that guaranteed people in London woke up on time. Meet the Knocker-Uppers—a group of hardworking individuals whose sole job was to make sure you didn’t sleep through your responsibilities. These early morning alarm clocks would quite literally knock on your door or window to rouse you from your slumber, often in the most peculiar ways.
In the 19th and early 20th centuries, Londoners working in factories, docks, or as servants in the homes of the wealthy couldn’t rely on mechanical alarm clocks, as they were often either too expensive or unreliable. That’s where the Knocker-Uppers came in. They were hired to ensure workers, most often in the poorer districts, started their day on time. And they did this job with a mixture of strategy, skill, and a lot of noise.
How Did They Work?
A Knocker-Upper’s method was simple, yet effective: they would arrive at their clients’ homes early in the morning—sometimes as early as 4 a.m.—and make sure their clients were up. But instead of simply knocking on doors like a modern-day door-to-door salesman, they had to be creative. One of their primary tools of the trade was a long, flexible stick called a “pecker.” This stick could be used to tap on windows, or in some cases, reach up to knock on the upper-floor windows of homes with multiple stories.
In wealthier areas, where the buildings were often large and multi-storied, Knocker-Uppers would sometimes use a pea-shooter, or even a small catapult, to fire peas or small stones at windows. The sound of the peas hitting the window would be enough to rouse the sleeping occupant. Imagine waking up to the sound of tiny pebbles tapping on your glass—an odd, but highly effective way to ensure you didn’t miss the start of your shift.
For the more modest homes, Knocker-Uppers simply used a wooden rod or a stick to knock on doors, or they’d shout out the name of the person they were waking, “Time to rise, Jack!” In many cases, it wasn’t an exclusive service. The Knocker-Upper might wake up several clients on the same street, moving from house to house, ensuring the workers got their start in the factory or workshop.
Who Hired Them?
Knocker-Uppers were often hired by individuals who worked long hours in the factories, where even a few minutes of lateness could result in a loss of wages or even dismissal. Factory owners knew they could count on these workers showing up on time if they were ensured an early wake-up call.
But the Knocker-Uppers didn’t serve just the industrial classes. Wealthier families who employed live-in servants also relied on these morning alarms. Since many of the servants worked late into the evening, they would be too exhausted to wake up early without help. The Knocker-Upper became a necessary figure in the routine of many households across London.
In fact, the job wasn’t just for the poor or working class; it was also common to hire a Knocker-Upper if you had a more irregular or nontraditional schedule. Professionals such as doctors, policemen, and firemen, who needed to be up at odd hours of the day or night, also employed these wake-up services.
An Endangered Profession
By the 1920s, however, this fascinating job began to fade into obscurity, largely due to the invention of the reliable mechanical alarm clock. As clockwork technology improved and the cost of these devices decreased, more and more people started to wake up to the sound of buzzing, ticking, or ringing instead of the persistent tapping of a human being.
The final blow to the Knocker-Upper industry came with the rise of the electric alarm clock in the 1930s. At this point, the Knocker-Upper was seen as an outdated and unnecessary figure. The task of waking up in the morning became a more solitary and personal affair—one done with a turn of a dial or the press of a button, rather than the sound of a stick or a shout from the street.
Mary Smith – The Last Known Knocker-Upper
One of the most famous late-era Knocker-Uppers in London was Mary Smith, who worked in the East End of London. She gained a bit of local renown for being one of the last of her kind to continue the profession into the 1940s. Smith, who was in her 60s at the time, was reported to be a reliable and punctual Knocker-Upper in the working-class neighborhoods of the East End.
Mary’s story was documented in newspapers, where her work was portrayed as a dying trade, with electric alarms soon to replace her services. As one of the final practitioners of this profession, Smith’s persistence in the face of changing technology highlighted the importance of Knocker-Uppers and their place in the community at the time.
The Legacy of the Knocker-Upper
Although the Knocker-Upper profession has long since disappeared, it lives on in the memories of those who remember waking up to the sound of knocking or pebbles. It’s easy to see how this quirky job could be romanticized, as it represents a simpler time when personal connections were key to starting the day. It also speaks to a unique moment in history when communities depended on one another for even the most mundane tasks—like waking up!
Today, we don’t have Knocker-Uppers, but we still owe a debt to their persistence and creativity. The next time you groggily reach for your phone to silence an alarm, think of those who woke up with the help of a steady tap on the window, a loud call from the street, or a well-aimed pea. The Knocker-Upper might be a thing of the past, but their role in helping Londoners rise and shine is an essential part of the city’s colorful history.
