Television in Uzbekistan
Was one of the first electronic camera
tubes developed in Uzbekistan in 1928? The following was pieced together
from various web pages:
Boris Grabovsky, son of the famous
Ukrainian poet, Viktor Popov, from a working class family, Nikolay
Piskunov, from a wealthy family and later a military officer, and Ivan
Belyansky, began working on an all-electronic television system, which
they named “Telephot”. Popov and Piskunov stopped working on the device
and went back to teaching, while Grabovsky and Belyansky continued to work
on television. Apparently Grabovsky was the primary inventor. (Hugo
Gernsback, the American publisher of radio and television magazines and
books, had coined the term Telephot in a 1909 article. A coincidence?).
Boris Grabovsky was born
on May 26, 1901 in Tobolsk, Tyuman Oblask, Russia. After the death of his
farther, Pavel Grabovsky, the family moved to Odessa, then to Kahrkov. In
1917, they had to move to Central Asia, to Kyrgyz, in the village of
Tokmak. He started his education in Tashkent special school. Then he
joined the faculty of the Central Asian University in Tashkent where he
worked with Prof. G. Popov. At the university he read articles by Boris
Rosing in the field of electronic telescopy.
While at the university they built a
device they called a “catode commutator” The device
had all the major elements of the modern television system: the camera
tube had a double-side photo layer and electrostatic deflection of an
electron beam.
The tests with the device were carried
out in the summer 1928 at the the house where the inventors lived with
their families, which is where the present Tashkent TV center is located.
The tests were sometime successful, and sometimes not. They televised a
moving hand, and on June 28, 1928, they televised the faces of Belyansky
and Grabovsky's wife Lidiya.
On August 4 they set up the camera and a
transmitter at a location outside, and set up a receiver about 500 meters
away. They then successfully televised a tram moving along Navoi Street.
They were issued a patent on July 30,
1928, which read: "The author of the device to transmit mobile picture at
a distance is the citizen of the Union of Soviet Socialist Republics."
By 1930 they were forced, apparently by
Soviet officials, to stop work on television.
On April 16, 1971 the director of
UNESCO's department of scientific information sent a letter to Belyansky
acknowledging the significance of his work in the development of
television.
A museum, named after Belyansky, is
located in Tashkent, Uzbekistan, features his work. The camera tube is
supposedly on display at the Museum of Communications in St. Petersburg,
Russia.
The Soviets were well known for
exaggerating their accomplishments in science and technology, so it is
hard to know how much of this is true. If Grabovsky did make a camera tube
in 1928, his accomplishment should should be recognized along with Philo
Farnsworth and Vladimir Zworykin.
