Career
In 1925, one of the pioneers of television Boris Rosing advised and helped him apply for a patent (issued under Number 5592) of a fully electronic television set called Telefot. In his method patented in 1925, Grabovsky proposed a new principle of the television imaging based on the vertical and horizontal electron beam sweeping under high voltage that is widely used in the modern cathode-ray tubes. A historian and ethnographer Boris Golender (Борис Голендер in Russian) in his video lecture described in details where and how the inventor Boris Grabovsky demonstrated a first fully electronic television set to committee and public in summer 1928.
Although this date of demonstration of the fully electronic television set is the earliest known so far, most of the modern historians claim that either Vladimir Zworykin or Philo Farnsworth were supposedly first.
Contribution made by Boris Grabovsky to the development of early television was acknowledged by the Government of the Union of the Soviet Socialist Republics and in 1964 he was awarded a prestigious degree "Honorable Inventor of the UzSSR". After the death of his father the next year, the family moved to Odessa then to Kharkov.
In 1917, they had to move to Central Asia, to Kyrgyz village Tokmak. He died in January 1966.
Boris Grabovsky started his education in Tashkent special school.
Then he entered preparational faculty of Central Asian University in Tashkent where he worked with Professor G. Popov. In the university he read articles by Boris Rosing in the field of electronic telescopy. Being excited by the idea of the transmission of images over a distance, he invented the cathode commutator, which was the first prototype of his transmitting tube.
