Friends!

Friends! Today is 116 years from the birth of Boris Grabowski, Ukrainian scientist who invented television.

Boris was born in the family of the famous Ukrainian poet Pavlo Grabowski. His poems are well-known by Ukrainians. Future scientist’s father was a revolutionary who fought for national freedom of Ukraine. Therefore in 1889 he was sent to Yakutia by the royal order and later in exile in Tobolsk. His wife Anastasia was near. There was born Boris Grabowski. Pavlo Grabowski died when his son was only 1,5 years. Then Anastasia and son moved to Odessa and then to Kharkiv.

In early 1917 Grabowski moved to the Kyrgyz village of Tokmak. In the 20's two-year Boris studied at a special school in Tashkent, where he was sent after his high ability in training. Subsequently, Boris entered the preparatory course of Central Asian University. In this place he worked as a laboratory and researcher in physics. Once in the library he found works of Boris Rozynh in electronic telescopes. Grabowski realized that for decades scientists were unsuccessfully working to create electronic television and wanted to invent it.

He made the first significant discovery in his 23. He invented the cathode switch, which became the basis for the transmission of television tubes. But then the work stopped - the boy lacked knowledge. Boris moved to Saratov, where his aunt lived. She introduced a young scientist with teachers of mathematics and physics Piskunov and Popov.

Together they began to make experiments. On the 26th of June, 1928 at 12.00 scientists witnessed the birth of the world's first electronic television. On a small screen was seen as another inventor Byelyanskyy removed and put cap. Transmitter was at the experimental station, and a receiver at the Ministry of Communications. This distance was only 30 meters, but this was the first transfer of the moving image. Two weeks later, the experiment was repeated on Tashkent streets, was filmed passing traffic tram. The invention was called "telephot".

The next logical step was to present "telephot" in Moscow. All necessary equipment was forwarded by mail. When the package was opened, it was found that the equipment was completely broken. The Commission, to which the invention showed Grabowski found him hopeless. There is a theory that the NKVD banned Boris telephot to develop.

At the difficult times, when he continued his projects, Boris was supported by Paton, who wrote that the idea for getting cathode beam has been successfully used in the Institute of Electric.

But the biggest blow was waiting ahead. A few years later Grabowski rad Mitchell Wilson's book. There were told about all his accomplishments and inventions, however... It told they were made in America by Russian emigrant scientist Vladimir Zvarykin. He started to fight for the truth. Only 35 years after the invention of telephot Boris Grabowski received a letter from the State Committee of the USSR electronics with the recognition and priority patent on the device for electronic telescopes. Later his role in the creation of television and acknowledged world.

In 1966, a year after the title of Honored inventor Boris Grabowski died.

I think everyone should know about the achievements of this outstanding scientist.
