Vladimir Zvorikin

Vladimir Zvorikin. Múrom, 1906.

Vladímir Kozmich Zvorikin (in Russian, Влади́мир Козьми́ч Зворы́кин; Murom, July 30, 1889 - Princeton, July 29, 1982) was a Russian-born American engineer who invented a cathode ray tube, in 1929, used in kinescopes. In 1923 he created a cathode ray tube for image transmission and the iconoscope was born, the first camera capable of transmitting video. Vladimir Kozmich Zvorikin is known by the nickname "the father of television".

Biography

Vladimir Zvorikin studied at the Imperial Institute of Technology in Saint Petersburg, where he was taught by Boris Rosing. He proposed in 1907 a television system using cathode ray tubes, which his student was going to take to a higher grade over the years. After graduating cum laude in 1912 in St. Petersburg, he moved to Paris to study at the Collège de France with Professor Paul Langevin, with whom he studied the use of X-rays.

World War I forces him to return to Russia to enlist in the army, where he eventually teaches at the army radio school, thanks to his studies both in Saint Petersburg and France. After the end of World War I, the Russian Revolution came, and Zworykin immigrated to the United States. There he earned a Ph.D. from the University of Pittsburgh.

He worked for Westinghouse, but couldn't convince them to carry out his television studies. In 1928, he met David Sarnoff of RCA who financed the project. Zworykin concentrated during those years on the development of substitute electronic devices, the results of which were the patent attempt (in 1923 and 1924) for two image tubes for the formation and reception of television images, which he called respectively iconoscope and kinetoscope.. After this he became part of the RCA staff and from 1933 he was known worldwide. In 1939, RCA inaugurated its television transmissions. In 1929, he was appointed head of the Electronic Research Laboratory at Camden. In 1947, they made him vice president and technical adviser of the company. He retired in 1954, being named honorary vice president. He died in 1982 in Princeton at the age of 94.
