Doorbell

William Murdoch, a Scottish inventor, was one of the first people to have a doorbell. Installed as part of his house built in Birmingham in 1817, it worked using a piped system of compressed air.

A precursor to the electric doorbell, specifically a bell that could be rung at a distance via an electric wire, was invented by Joseph Henry around 1831

British children over the centuries have always enjoyed ringing doorbells and then running away. However they are breaking the law according to the Town Police Causes Act of 1847.

Orville Wright died from a heart attack while fixing the doorbell to his home in Oakwood, Ohio in 1949.

82% of teenagers don’t ring the doorbell, they text or call to say they’re outside instead.
