The knocker-upper was a working professional in British industrial cities from the nineteenth century into the early twentieth. Their job was to walk the streets before dawn and wake clients for their shifts, using long poles, sticks, or in some cases pea shooters to tap on windows. The service was paid for by the week. Mary Smith of Leman Street in East London became the most documented knocker-upper, known for using a pea shooter to reach upper-floor windows without disturbing neighbors on lower floors.
Daniel and Mom trace the knocker-upper profession from its industrial origins through its tools and techniques, including the question of who woke the knocker-upper. The profession faded as alarm clocks became affordable, with the last known knocker-uppers working into the 1970s in some parts of Britain.
MomDaniel, I have a question for you. Before alarm clocks existed, how do you think people woke up in time for work?
DanielWow, Mom, that is such a random question. Did they use roosters? The sun? Someone banging on the door?
MomThat last one. Literally. There was an entire profession whose job was to walk through the streets before dawn and wake people up. Are you sure?
DanielThat was a real job?
MomYes, a very real job. They were called knocker-uppers, and some of them were still doing it in the 1930s.
DanielNow that's interesting. How did it work?
MomYou would pay someone, usually a few pence a week, and every morning before your shift, they would come to your window and knock until you got out of bed. They used long bamboo poles to reach upper floor windows, rattles, soft hammers, some of them used pea shooters, tubes they would blow dried peas through to rattle against the glass.
DanielThey shot peas at people's windows?
MomYes, they did. The most famous one, a woman named Mary Smith, who worked in London's East End, used a pea shooter every single morning. She rose at three in the morning, charged six pence a week, and would not leave a client's window until she was certain they were awake.
MomHer nearest competition was an old man, three miles away, who used a fishing rod.
DanielA fishing rod?
MomTo tap on upper floor windows without waking the neighbors below. And in County Durham, miners had slate boards set into the outside walls of their houses. They would chalk up their shift time the night before, so the knocker-upper knew exactly when to come.
DanielSo people built their whole morning routine around the stranger who would come knock on their window.
MomFor countless workers during the Industrial Revolution, the knocker-upper was as essential as the factory itself. Workers in mines and mills started shifts at strange hours. Missing the knock could mean losing your job.
DanielOkay, but here's the obvious question. Who woke the knocker-upper?
MomThere is actually a real tongue twister about this from the 1800s.
DanielThat is a real thing?
MomA real thing. The honest answer is that many knocker-uppers stayed awake until their rounds were finished or relied on their own body clocks after years of the same routine. Some also had other work or performed early morning patrols. Some woke each other. Mary Smith's daughter eventually took over the job and kept going well into the 20th century, using the same 60-year-old pea-shooter tube that had been passed down.
DanielShe inherited the pea-shooter, the whole job, and the tool.
MomYes, the family profession and the family tool. But here's the thing that surprises most people. Alarm clocks existed before knocker-uppers disappeared.
DanielWait, so why were people still paying for knocker-uppers if alarm clocks already existed?
MomBecause early alarm clocks were expensive, a factory worker could not easily afford one. And they were unreliable. They needed winding. They ran fast or slow. They could not always be trusted. Paying a penny or two a week for a knocker-upper was cheaper and more reliable than owning a clock.
MomThe Guardian even ran a story in 1914 warning that the cheap American clock was going to kill the knocker-upper industry.
DanielSo the knocker-upper and the alarm clock existed at the same time for decades, and people chose the human one because it was more dependable.
MomUntil the clocks got cheap enough and reliable enough that they weren't. And then, gradually, without any announcement, the knocker-uppers stopped being needed.
DanielThey didn't fight it. They just became unnecessary.
MomThat is how most jobs replaced by technology disappear. Not with a protest. Just with a slow mourning when no one calls for them anymore.
DanielThat is kind of sad.
MomA little. And also remarkable that for over a hundred years, an entire city could wake up because strangers walked the streets before dawn, in the cold, shooting peas at windows. There is something quietly wonderful about that. So, Daniel, what is one thing you are taking with you today?
DanielKnocker-uppers were real people paid to walk the streets before dawn and wake workers up using poles, rattles, and peashooters. And they kept working even after alarm clocks existed because early clocks were too expensive and unreliable. They only disappeared when clocks got cheap enough to trust.
MomAnd somewhere in London, a 60-year-old peashooter was passed from mother to daughter.
