apr 4, 1774 - Electric Telegraph

Description:

Georges Louis Lesage patents the electric telegraph. Electric Telegraph uses electric signals to send communication via radio or line. This was used as a communication of people but only inside the same country.

My own experience: I remember seeing this device in a history documentary of WW1 as this was around the era of its use
