Well besides a rooster. The knocker-up also sometimes referred to as a knocker-upper. This profession was prevalent in both England and Ireland having started during the early days of the Industrial Revolution and lasted into the beginnings of the 20th Century as late as the 1920’s. Before alarm clocks were both affordable, and reliable, it was the job of the knocker-up to rouse his sleeping clients from their slumber so they could get to work on time. The knocker-up often used a long stick with wire or knob to wake those clients that required his services. More often the sticks were made of lightweight bamboo, and much longer to be able to reach windows on upper floors. In return for the provided service the knocker-up would be paid a few pence a week. The knocker-up would often not leave a client’s window until they were assured the client had been awoken and would not fall back asleep. Mary Smith and others earned six pence a week shooting a pea into the windows of the sleeping workers.
