The telethrophone or the telephone was invented in 1854 by the Italian inventor Antonio Meucci. He built it to connect his office with his bedroom so he could talk to his wife, who was immobilized in bed due to illness.
The device could transmit acoustic signals at a distance by means of electrical signals. It was the forerunner of today’s the telephone, but Meucci had no money to patent the invention, so its discovery was never recognized.
For a long time, Alexander Graham Bell was considered the inventor of the telephone, but only because he was the first to patent the device in 1876.
It was not until 2002 that the United States Congress approved the recognition of Antonio Meucci as the inventor of the telephone.
Origin of the phone
The telephone is an invention that began as child’s play, in the early 18th century. In their day, many researchers described electrical voice transmitters from theoretical approaches, but without substantiating such hypotheses.
The first and perhaps most important was the Italian Antonio Meucci, who in 1854 invented the telephony.
Meucci invented an artifact capable of communicating his voice from the ground floor of a house to the upper floor. But being poor, he did not have enough money to be able to patent it. This fact was later used by other inventors who used the principle of operation of this mechanism, as we will see below.
For many years there was (and is still disputed today) a great legal dispute to decide who had been the true inventor of the telephone.
A few years later, in 1863, the German Johann Philipp Reis even used the term telephon to refer to a vibrating membrane that was opened and closed by means of an electrical circuit and reproduced musical sounds. But Reis never took this seriously and never considered it a mere toy.
Who invented the telephone
The inventor of the telephone is Alexander Graham Bell. He was a British scientist who patented the invention of the telephone on January 14, 1876, in New York (United States of America).
Not if great controversy, since that day two men, Graham Bell and Elias Gray , appeared at the New York Patent Office to register an unheard of and unusual invention: the telephone under patent number US178399A.
But Bell arrived at twelve noon and Gray two hours later. That difference enshrined the young Scotsman, Bell, as the father of the telephone, the most important invention of his time.
This invention used electricity to talk at a distance and start a telephone network. Dialing a few numbers can put people who are physically far apart in verbal contact.
Bell and Gray litigated for ten years, but in the end, the verdict favored Bell, who in a short time became a millionaire thanks to this revolutionary and novel invention.
The first call
The first wireless call took place in 1973 thanks to Martin Cooper, an engineer for the telecommunications company Motorola.
During the following years, technological advances made it possible to develop the first mobile phone models, which allowed communication from anywhere. At that time, the call could have a maximum duration of 30 minutes.
From there, in the 1990s there were already countless brands that sold mobile phones. Some were more compact and even had a lid to protect them from shocks.
The next big addition to mobile devices was the color screen . But it was not until this century that the first phone with a built- in camera appeared that allowed taking pictures.
Then came the text messages and multimedia messages (which could incluirimágenes and sound). In 2007, up to 1.9 trillion messages were recorded worldwide.
In less than 25 years, one in every fifty people already had a telephone in the United States. Bell was not yet thirty years old when he already had an immense fortune.
The first telephone exchange was installed in New Haven, in the US state of Connecticut, in January 1878. It had twenty-one subscribers, including the novelist Mark Twain.
When the person originating the call picked up his receiver, an electrical switch was activated in the switchboard that warned the operator, and she moved a lever and asked the subscriber who he wanted to talk to.
At that time, there were only eight individual telephone lines shared by various subscribers. The operator had to follow the conversation from time to time because there was no way of knowing when the conversation between subscribers had ended.
The telephone exchanges Automatic, calls without operator or delay, were devised in 1889 by a mortician Kansas City, Almon S. Strowger. And its origin is the most curious.
Intrigued that all requests for mortuary services went to the competition, he discovered that his competitor’s wife was the local operator. She diverted orders to her husband’s phone. She was the first to know of the gossip, hoaxes and news circulating around the city, including the deaths of the entire town.
Smart phones and watches
Steve Jobs revolutionized the mobile phone industry and new technologies in 2007 when the first iPhone model was introduced .
Apple’s phone included the touch device , internet browsing, and other service applications .
That completely changed the concept of the “mobile phone“: it was not only used to call or send messages but could do many more things. In 2010, practically all smartphones had a touch screen and internet connectivity.
Many models and many brands broke into the technology market in the wake of the iPhone. We went from using it to call to not taking off from the mobile all day.
The mobile phone world is constantly changing and evolving . The latest innovations include smartwatches or smartwatches connected to mobile phones, curved screens or water resistant devices.
The Mobile World Congress offers the opportunity to see all the news of an invention that was born to connect people and is now part of our lives at all hours.
