Although there are still disagreements, the official birth of the telephone continues to be attributed to the Scottish-born scientist Alexander Graham Bell, and it had the providential help of Dom Pedro II to become popular.<\/p>\n\n\n\n
Boston, capital of the state of Massachusetts, March 7, 1876. A 29-year-old young scientist, born in Scotland and the son of intellectual parents, received from the United States Patent Office registration number 174,465 for the creation of \u201cthe method of, and apparatus for, transmitting vocal or other sounds telegraphically, causing electrical undulations similar to the vibrations of the air accompanying the said vocal or other sound.\u201d Three days later came the phrase that would change the world: \u201cMr. Watson, come here, I want to see you.\u201d<\/p>\n\n\n\n
On one end of the line was Alexander Graham Bell; on the other, his assistant Thomas Watson. Between them, a wooden and metal device with a receiver and a transmitter connected by wires. Although the dispute over the invention still generates controversy 150 years later, it was on March 10, 1876, that the telephone was officially born.<\/p>\n\n\n\n
The immediate reaction was paradoxical. On one hand, the press of the time welcomed the invention with enthusiasm, publishing headlines describing it as something \u201cmagical.\u201d On the other hand, the general public viewed it with suspicion, as a kind of \u201cwitchcraft\u201d that allowed people to speak across miles. Faced with this impasse, the telephone remained sidelined for months\u2014until an unlikely promoter changed the course of history without even realizing it.<\/p>\n\n\n\n
His name? Dom Pedro II, the Emperor of Brazil. During a visit to the Centennial International Exhibition in Philadelphia in June of that same year, the Brazilian monarch walked among the stands displaying inventions such as the electric lamp and Heinz ketchup, until he stopped at Bell\u2019s exhibit. Curious about the apparatus, he was invited by the inventor to try it. He moved about 100 meters away and waited while Bell recited, from the other end, a verse by William Shakespeare. \u201cMy God, it talks!\u201d he reportedly exclaimed.<\/p>\n\n\n\n
The emperor\u2019s astonishment was so great that it led him to bring the first telephone devices outside the United States to Brazil, turning the country into a kind of showcase for the new technology. The elegant device acquired by the emperor to communicate with his allies can still be seen on display at the Telecommunications Museum in Rio de Janeiro.<\/p>\n\n\n\n
The boom of the invention<\/p>\n\n\n\n
In the following decades, the first telephone exchanges began to appear, still dependent on human operators to connect calls and largely restricted to authorities and members of the aristocracy.<\/p>\n\n\n\n
Starting in 1910, the telephone became a business tool and a symbol of social status for the elite, with wall-mounted devices and the first \u201ccandlestick\u201d models. Only four decades later did it become more affordable and start to appear in middle-class homes.<\/p>\n\n\n\n
By 2014, when there was already one mobile phone per person on Earth, landline devices began to fall out of use. However, according to estimates by Brazil\u2019s National Telecommunications Agency (Anatel), there are still at least 20 million of them in the country. Worldwide, \u201conly\u201d one billion remain active.<\/p>\n\n\n\n
Wireless and out of control<\/p>\n\n\n\n
There is a Buddhist proverb that says: \u201cIf the student does not surpass the master, the master has failed.\u201d In the tireless machinery of science, there are many stories of students who went further than their teachers, whether in fame or in what they (re)invented. This is the case of Martin Cooper, an American electrical engineer credited with inventing the mobile phone\u2014the definitive version (until proven otherwise) of Bell\u2019s legacy.<\/p>\n\n\n\n
Unlike his predecessor, Cooper\u2019s creation in 1973 was made in broad daylight, before numerous witnesses, and already with the expectation of becoming a commercial phenomenon. The innovation was announced in New York by its creator during a press conference, where he made a historic call using the Motorola DynaTAC\u2014a device weighing nearly 2.5 kg with a battery that allowed only 20 minutes of talk time.<\/p>\n\n\n\n
What followed would once again change the course of history. Devices gained new shapes and functions year after year until, in 2007, an innovation sparked the last major revolution: the end of physical keyboards and the introduction of touchscreen displays, inspired by an older technology from the aviation industry.<\/p>\n\n\n\n
Today, there are more mobile phones than people in the world: around 12 billion active lines in 2026.<\/p>\n\n\n\n
Nomophobia<\/p>\n\n\n\n
Dependence on the device has become one of the \u201cills\u201d created by newer generations\u2014and it even has a name: nomophobia. A 2024 study by nomophobia.com, a website dedicated to the subject, reveals that 60% of Brazilians report anxiety when they are without their mobile phones.<\/p>\n\n\n\n
For 85% of Brazilians, mobile phones facilitate financial transactions through mobile payments. In addition, 70% use their devices for entertainment\u2014such as listening to music, watching movies, and gaming\u2014while 57% say they contribute to education by enabling distance learning. Finally, 30% reported having met their partner through social networks or dating apps.<\/p>\n\n\n\n
Nomophobia, beyond anxiety, can cause panic, depression, social isolation, and sleep disorders due to blue light exposure. This dependency also leads to irritability, reduced concentration, neck and back pain, eye strain, and decreased academic or professional performance.<\/p>\n\n\n\n
Today, a new movement is emerging worldwide that questions what Bell and Cooper created as a synonym for quality of life. \u201cForgive us, science,\u201d say its advocates, \u201cbut blessed are those who do not need a mobile phone.\u201d<\/p>\n\n\n\n
Like father, like son<\/p>\n\n\n\n
The history of the telephone also involves the dispute raised by Italian inventor Antonio Meucci, who for many years claimed to have developed a voice transmission system before Alexander Graham Bell registered his patent.<\/p>\n\n\n\n
Meucci had emigrated to the United States and, in the 1850s, was working on a device he called the \u201ctelettrofono,\u201d capable of transmitting voice electrically between rooms in a house. The device was initially created to allow him to communicate with his wife, who was ill and stayed in a different room.<\/p>\n\n\n\n
According to Meucci\u2019s supporters, he presented prototypes and, in 1871, filed a kind of preliminary patent notice known as a caveat, which temporarily protected his idea. However, he was unable to pay the fees required to renew it in subsequent years. There are also accounts that models and documents were delivered to a laboratory associated with Western Union and later disappeared, fueling suspicions that his work may have been appropriated or ignored before the official telephone patent.<\/p>\n\n\n\n
The controversy persisted for more than a century and returned to public debate in the early 2000s, when the United States House of Representatives passed a symbolic resolution recognizing Meucci\u2019s contribution to the development of the telephone. The measure did not revoke Bell\u2019s historic patent, but reinforced the idea that the invention was the result of parallel experiments and typical scientific disputes of the time, when multiple researchers were seeking similar solutions for transmitting voice over a distance.<\/p>\n","protected":false},"excerpt":{"rendered":"
