In England and Ireland there was a profession that was called Knocker-up or Knocker-upper.
Those were specially trained people who woke everybody up for work, instead of an alarm clock.
She was originated in the time of the Industrial Revolution and existed until the 20's of the 20th century.
This position was occupied mostly by elderly people, but for an additional fee the work was entrusted to the local constable.
Knocker-uppuers used mainly long bamboo sticks, batons, sticks, but sometimes to wake residents of the upper floors they shot peas into windows.
