The day the telephone was patented – level 2
Alexander Graham Bell started his experiments in 1873. He was trying to find a way to send sound from one machine to another. He spent all his free time on such experiments, but for a long time, he wasn’t successful.
Then in June 1875, Bell successfully sent a tone between two machines. Nine months later, on March 7, 1876, Bell went to the patent office. He wanted to patent his idea of a telephone.
On the same day as Bell, another inventor, Elisha Gray, also went to the patent office to patent his telephone. Unfortunately for Gray, Bell arrived at the patent office 2 hours before him.
Bell then offered the telephone to the US and British governments, but they weren’t interested in this new machine.
A year later, Bell demonstrated his telephone at the exhibition in Philadelphia and won the first prize. Soon after that, phones started to be mass-produced and introduced to other countries. Bell became a rich man.
For mankind, a new era of fast long-distance communication began.
