Within a year, he started working for Westinghouse Electric and Manufacturing in Pittsburgh. In 1919, during the civil war in Russia after the Bolshevik Revolution, Zworykin emigrated to the United States. As a result of these studies, revolutionary changes took place in the fields of biology and medicine. Zworykin did not invent the electron microscope, but he became the leader of a team that made significant improvements to the device. Iconoscope and the electron microscope Zworykin, in front of the first scanning electron microscope, circa 1945. Although Rosing was a pioneer, his system was rude and clumsy. ![]() Swinton never implemented the system he developed. It was possible to get a moving image by scanning the entire screen several times per second and changing the density of the electron beam. The inside of the screen was covered with chemical compounds known as phosphorus that radiate from the striking electrons.Įlectromagnets placed around the tube controlled the direction of the electron beam (the television signals sent to the magnet allowed the beam to scan the screen in horizontal lines). The cathode ray tube was a glass tube that was deaerated, and the electron beam struck a flat screen. In fact, in 1908, in a letter published by Scottish engineer AA Campbell Swinton (1863–1930), the first thoughts on the “ electric image” were summarized, that is using the cathode ray tube technology founded in 1897 by German physicist Karl Ferdinand Braun (1850–1928). In different countries, various scientists were contemplating the same project. Rosing gave this invention the name “electric telescope,” which is one of the first names for television. In this institute, one of Zworykin’s teachers, Borin Rosing (1869-1933), showed his student a project he was working on in secret. In 1912, he received an engineering degree from the St. In his childhood, Zworykin was engaged in the installation and repair of electric doorbells on family-owned steam vessels. Vladimir Zworykin was born in the town of Murom, which was part of the Russian Empire at the time. ![]() One of the most important pioneers was the Russian-born inventor Vladimir Zworykin, who also contributed greatly to the development of the electron microscope. Dozens of scientists have contributed to the development of television. The history of this invention is quite complicated. In the 20th century, television has changed the lifestyle of hundreds of millions of people.
