This event takes place in the city of Boston between Alexander G Bell who was in his laboratory and Mr. Watson located two miles away.
The following year, Bell Telephone Company was founded and in about 10 years reached about 150,000 people in the United States who purchased their telephone.
On January 25, 1915, thus 40 years later they achieved their first transatlantic telephone conversation, Mr. Bell and Mr. Watson had the honor of being the first people to do so.
An important fact is that the first effective communication was achieved in March 1876 where the first words that were said were "Mr. Watson, come here, I need you" this happened through the wires that had been arranged inside a house between a room on the upper floor and a room on the lower floor.
This first apparatus was only arranged for voice transmission in one direction only.
Bell was born in 1847 in Edinburgh, Scotland, and became an expert in sound and public speaking. His understanding of sound helped him teach the deaf and later invent the telephone.
