Many people know that Alexander Graham Bell invented the phone, but if you look, the idea was developed even when it was very small. It turns out that he simply appropriated this development. So who came up with the first phone? It was Antonio Meucci. How has a long telephone history developed? Who invented the mobile phone? Let's try to figure it out.
Phone story
The development of a telephone would have become impossible if people had not learned to convert sound vibrations into electrical impulses. In 1833, C. F. Gauss and V. E. Weber in Göttingen did this. In 1837, they discovered a phenomenon that was later called "galvanic music." The electrical circuit consists of a horseshoe magnet, tuning fork, and a galvanic cell. During the vibrations of the tuning fork, which open and close the circuit, the electromagnet began to make a melodic sound.
The first words that were said over the phone in 1861 went down in history as winged: "The horse does not eat cucumber salad." Therefore, in which year the telephone was invented, it is not difficult to calculate.
Poor genius
On April 13, 1808, the brilliant scientist Antonio Meucci was born in Florence. During his life, he founded a factory of stearin candles, a beer factory, in 1860 he opened a factory that produced paraffin candles, which became the first in the world.
The year 1854 made Antonio think about developing a method for transmitting audio signals from a distance. This thought was prompted by his wife’s illness, which was severely tormented by rheumatism. Sometimes she could not even leave her room.
Not enough money
In 1866, an accident occurred at his factory: a boiler exploded. Because of this, Meucci was hospitalized for three months. Subsequently, he was fired from his job, and his wife had to sell some of his developments in order to gain at least some money. Among them were samples of the future phone. Meucci continued to work on development, and in 1871 he applied to the United States Patent Office. Lack of finance affected the loss of a patent in 1873.
11. 06. 2002 in the United States adopted a resolution on who invented the phone. Congress recognized the inventor of Antonio Meucci. The reason for the Italian's non-recognition by the author of the development during his life was an insufficient knowledge of the English language to understand the subtleties of legal issues. He could not hire a lawyer and defend his rights in court. Even after a detailed exposition of all the nuances of the development, which a priori proved its absolute rightness, he did not have enough only 10 dollars to pay the tax. If he found the right amount, then the whole world in 1874 would recognize the primacy of Antonio Meucci, not Bell.
Legal owner of the development
So, in 1876, two applicants A. Bell and I. Gray appeared at once in the Patent Office. Within a few days, Bella was issued the copyright certificate for "a telegraph device that can transmit human speech." The advanced model consisted of a wooden stand, an acid reservoir (this served as a battery), an auditory tube and copper wires. The creator nicknamed his model "gallows" for its unusual shape. Gray was denied a patent.
For a long time, the primitive model of the phone remained in the shadows. And only in June 1876 he still decided to show it at an exhibition in Philadelphia. The guests remained indifferent to the presented device until the end of the exhibition. Already during the closure, a tall man stopped by the phone, who turned out to be the emperor of Brazil. He was very interested in the novelty exhibited and leaned the earpiece against his ear. What was his surprise when he heard a human voice there! From that moment, the novelty became a worldwide sensation and quickly gained popularity.
Thus, we found out who invented the phone, but the modern communication device is very different from the first. The technologies have developed so much that there is practically nothing left with the usual models for us, except for the principle of operation. And who invented the mobile phone, we will find out further.
Mobile Development
A cell or mobile phone is designed to work in cellular communications. For its implementation by telephone using conventional telephone communication and a radio transceiver.
Among all types of mobile communications, cellular is the most common. A mobile phone is often called a cell phone, although this is not entirely true. Trunk communications, and radiotelephones, and satellite phones are mobile.
Not many people know who invented the cell phone and when. Today without him we cannot imagine our life. And the story began, it turns out, not so long ago.
The first idea of telephone communication appeared in 1946 with AT&T Bell Labs. The company developed the world's first radiotelephone service. It was a telephone hybrid and a radio transmitter. A radio station was installed in the car, and that was the only way to make a call. It was impossible to speak at the same time, because in order to say, you had to press a button, as in a walkie-talkie, then, having released it, you could hear a message in response. The device weighed 12 kg, was located in the trunk of the car, and the remote control and the handset were carried into the passenger compartment. For the sake of the antenna, we drilled holes in the car!
Who invented the cell phone?
Already in 1957, the Russian scientist L. Kupriyanov experimentally created a sample of a mobile phone. His weight was 3 kg. Later, the weight of the device was reduced to 0.5 kg, then to 70 g. In 1973, the world's first portable phone started, the first call on which was made on April 3. Motorola DynaTAc, this is the name of this device, it had 12 keys, it lacked a display and functions. It was possible to talk only 35 minutes and charging required 10 hours of waiting.
1984 was marked by the appearance on sale of the final model of the mobile phone DynaTAC 8000X. Its price was $ 3995! In 1989, Motorola MicroTac was launched.
Latest phone designs
Who invented the phone, we found out, and how did the touch phones come about? In 1998, the first touchscreen phone saw the light . Although they developed it back in 1993 at IBM, which was engaged in computer technology. The touch screen responds to the touch of a finger to enter any information.
It is definitely difficult to say who invented the touch phone; most likely, it was Samuel Hurst. In 1971, he developed an elograph - a graphic tablet. In 1972, the Americans introduced the first touchscreen phone. After 10 years, the first touch-screen TV was exhibited at the fair.
In 2007, the LG KE850 Prada touchscreen phone appeared, which had an excellent design and had great features. The phone could be controlled simply with a finger, not a stylus.
So, gradually the phones began to improve, many manufacturers appeared, the gadget became an indispensable thing for us, and whoever invented the phone, many forgot.
