Who invented television and in which year?

Today the TV does not surprise anyone. This is a box or even a small panel that allows you to show movable pictures. It is difficult to imagine that just a little more than a century ago such a technology was not in principle. Only thanks to the huge amount of research we have the opportunity to enjoy television.

About people who gave us the opportunity to transfer images from a distance, and will be discussed in this article.

At the origins

Who invented television and in which year? A lot of people asked this question, but not everyone could give an exact answer to it.

Until now, the question of where the television was invented was also open. The answers can not be unambiguous. All because not one person invented the first television. This is laborious work of many people.

Where was television invented? Many nations of the world are fighting for this right, in each of which an entire army of scientists has worked on this issue. But first things first.

How it all began

The very first who invented television, we can consider a Swedish chemist, whose name was Jens Berzelius. The scientist put many experiments in his laboratory, as a result of which he discovered a previously unknown chemical element, which was called "selenium."

The importance of this event can not be overemphasized. It was noted that this element conducts an electric current, depending on the amount of light acting on it.

Without it, image transmission would not be possible.

From theory to practice

Boris Lvovich Rosing - that's who invented television, - historians will assert. And they will not be far from the truth.

The biography of this physicist and inventor, who actually gave us the opportunity to spend the evenings at the blue screen, should be studied deeper.

Boris Lvovich Rozing was born in 189 in St. Petersburg.

Almost all his life he devoted to work at the institute. This is the Petersburg technological, and the Arkhangelsk forestry, and many others, where he was invited as an honorary lecturer. The scientist defended his thesis.

His work was devoted to the study of magnetism, radio engineering, electricity, molecular field, ferromagnets, quantum physics, dynamics.

The idea to transfer the image to a distance came to Boris Lvovich in the year one thousand eight hundred and ninety-seven. He could not imagine his experiments without the electron-beam tube, which had just been invented, as well as studies of the photoelectric effect of the physicist Alexander G. Stoletov.

His success in studying the issue was great. Already in 1918, the world was presented with the technology of creating an image using an electron-beam tube with a fluorescent screen and rotating mirrors. The inventions of physics were patented and recognized in the United States of America, Great Britain, Germany. The experiment was a display of gray bars on a black screen. It seems that everything is so simple. But for that time it was a grand breakthrough. About the talented scientist began to speak in the whole world.

In just four years the physicist managed to transfer the image to a distance. Most likely, none of the readers have no doubt who invented television.

In this same year, nine hundred and eleven, Rosing made a transition from mechanical to electronic systems.

Until his death in 1933, the physicist continued to create and improve his instruments, developed new methods of modulation, the construction of tubes and circuits.

First experiments with a picture

Who invented television first, so this is the famous American inventor, Mr. Kerry, many researchers believe. The result of his experiments was the first working system, through which he was able to transmit an obscure, but still an image.

About the inventor of television, the descendants of the inventor Paul Nipkou can enter into a dispute. His experiments were much more perfect, although the principle of operation of the device was identical to that of Mr. Kerry. Paul gave his invention the name "unfolded image." In the courtyard stood a thousand eight hundred and eighty-fourth year.

A new term

The very term "television" is attributed to the Russian engineer Konstantin Dmitrievich Persky.

Before that, scientists used complex expressions like "long-sightedness" or "electric telescopy."

It is believed that he first introduced it into use in August 1900. This was done within the framework of the International Electrotechnical Congress in Paris. The word really pleased the participants, and they quickly spread it in their circle of communication upon their return home.

The report on "vision at a distance" was conducted in French.

A year earlier, Konstantin Persky received a patent for one of the methods of image transmission. Inspired by his success, the engineer enthusiastically told his European colleagues about the colossal opportunities that his technology could give humanity.

About the scientist is known a lot. Konstantin Dmitrievich was a descendant of a noble family, his ancestors served the most great prince Dmitry Donskoy.

Prior to devoting his life to inventions, Perski managed to finish the Mikhailovsky Artillery Academy, and then applied his knowledge during the Russo-Turkish War, where he was even awarded the Order "For Bravery."

After returning from the battlefield, Konstantin Dmitrievich chose to join the military track with science and at the same time become an active member of the Petersburg technical and electric communities.

The most striking achievement in his work was an extensive report titled "The Current State of the Issue of Electric Vision for Distance," which he successfully represented in various educational institutions at home and abroad.

Although the occupation of physics did not prevent the scientist from improving in the military field. In particular, he received a medal of the Chicago World Exhibition for a warning device from attempts to secretly enter the premises.

The inventor did not become in 1906.

Optimistic results

On the question of when John Logie Baird invented television, there will be fans of his talent who will confidently say that this is one thousand nine hundred and twenty-third year. It was then that the scientist was able to transmit the image on the cable laid to his colleague, Charles Jenkins, in the United States of America.

But television is not just the transmission of electrical impulses over wires. In order to run them, you first need a television camera.

Connoisseurs say with confidence: the Russian scientist, whose name was Vladimir Zvorykin, invented television in 1931 at the facilities of his enterprise Radiocorporations of America. But this is a controversial issue, because in fact at the same time another inventor, Phil Farnsworth, is constructing a similar device.

The name of the sponsor of the Russian scientist who believed in his very futuristic and incredible idea is David Abramovich Sarnov, an American communications specialist and businessman. It was thanks to his financial support that the world saw most of the inventions of Vladimir Zvorykin.

The first video camera

The first cameras were named "inkoscope" and "image-transfer tube".

Over the next fourteen years, the devices will undergo serious modifications and will have a structure similar to that used in modern devices.

They are based on the cathode-ray tube, due to which, in fact, the image is transmitted to the viewer.

Color television

Many believe that color television was invented by Soviet engineer Hovhannes Adamyan.

In the far one thousand nine hundred and eighth year the inventor received a patent for the signal transmission device he created. The invention could transmit at that time only two colors.

But nevertheless it will be more correct John Lopey Brad to consider those who invented television in color. It was this man who connected the green, blue and red light filters in such a way that they could broadcast various combinations.

Interesting facts about television

Black and white television broadcasters used green lipstick. The red color on the screen looked very light and faded. After long experiments and tests, they came to the conclusion that it is the green that is most harmonious for color reproduction.

In occasion of, where and what exactly transfer in color left on screens first, there are disputes. Most often the opinion is that it was a football match of the English league.

A full-fledged permanent broadcast began in the year nineteen-fortieth in the United States.

The first commercial program was released in 1951 in the USA. It was an entertaining show featuring celebrities on the CBS channel.

Let's summarize the data

In the article there are names of many great people who worked at different times in laboratories of different countries and continents. Each of them made a significant contribution to the development of television. Without the works of these wonderful, purposeful people, the transfer of the picture is impossible.

Do not give out one. Thanks to all these studies, today we have the opportunity to use such a commonplace phenomenon as television.
