35. A Knocker Upper
Rare Historical Photos
Before the days of alarm clocks, Knocker Uppers could be seen on the streets in the wee hours of the morning tapping on windows to wake up families. A common sight in Britain, the Knocker Upper became prevalent during the rise of shift work. The odd hours for sleeping opened up a need for a third party to help with getting to work on time. Their jobs lasted well into the industrial revolution. Losing their careers to alarm clocks, the knocker uppers are now a thing of the distant past.
