In 19th-century England, oversleeping was not just an annoyance — it could cost you your wages or your job. And since most workers could not afford a clock, someone else had to do the job: the knocker-uppers, people hired to walk the streets at dawn and tap on windows with long bamboo poles, soft hammers, or even pea-shooting blowpipes, with enough precision to wake only one tenant without alerting the one upstairs. 🪟
Some began their rounds at 3:00 in the morning. Mary Smith, from London’s East End, charged six pence a week for this service in the 1930s. ‘Granny Cousins’ did the same in Poole, Dorset, waking brewery workers until 1918. For many women of the Victorian era, the trade represented something unusual: economic independence of their own. Charles Dickens mentioned them in ‘Great Expectations’ in 1861, and there are records that two knocker-uppers were the ones who found, at 3:45 AM, the body of Jack the Ripper’s first victim in Whitechapel. 😮
The trade gradually disappeared from the 1920s onward, when electricity spread and clocks became cheaper. In some towns it survived until the 1960s-1970s. Today, the closest thing that taps on your window at 3 AM is a notification from your phone. ⏰
