Boris Rosing

April 23, 1869 in the family of L.N. Rozing, a St. Petersburg official, was born the son of Boris Rosing - the future inventor of television. The boy grew up alive and inquisitive, successfully studied, was fond of literature and music. But his life turned out to be connected not with humanitarian, but with exact sciences.

After graduating from the Physics and Mathematics Faculty of St. Petersburg University, Boris Rosing was carried away with the idea of transmitting images to a distance. After a while he comes to the conclusion that it is possible to transfer images only with the help of an electron-beam tube known as a physical device from the end of the 19th century, and also by using the phenomenon of an external photoelectric effect discovered by A.G. Stoletov. Hundreds of experiments, many hours of restless creative thinking preceded the moment when Boris Rosing decided to publicly announce his research and the method of "electric transfer of images".

In 1907 he received in Russia a privilege (patent) for this method. To display the same image on the screen as in the transmitting device, Boris Rosing built an electromagnetic deployment device-coils that deflected the electron beam in Brown's tube. The number of scanning lines was only 12 (in modern television systems - up to 800). By 1912, Boris Rosing developed all the basic elements of modern black and white television tubes. His work became known in many countries, his patent was recognized in Germany, Britain and the United States. Boris Rosing died in 1933.
