7 jan 1816 ano - First Working Electric Telegraph

Descrição:

The very first working method of communication through an electric medium was developed by an English meteorologist by the name of Francis Ronalds. He appealed to the British government with his invention but was told that it was no longer required now that the Napoleonic wars were over. He never patented so eventually, his system was patented by others.
