Mono Monday 19th Century Inventions

In 1817 William Murdoch, a Scottish inventor, obviously was having problems with deliveries - 


“Sorry we missed you …”, no you didn’t, I was here all the time!!


- so he installed a loud doorbell that worked using a piped system of compressed air. 

A precursor to the electric doorbell, a bell that could be rung at a distance via an electric wire was invented by Joseph Henry around 1831. By the early 1900s doorbells had become commonplace.
