Isaac Schoenberg was born on February 29, 1880 in Pinsk. After graduating from the Kiev Polytechnic Institute, Isaac Schoenberg came to St. Petersburg and for ten years worked as a Chief Engineer at the Russian Society of Wireless Telegraphs and Telephones, was engaged in the construction and equipment of the first radio stations in Russia. After moving to the UK, he was in charge of the patent department of the Marconi Wireless and Telegraph Company, but soon he was offered to head the patent department of Electric and Musical Industries, which initially created and produced sound recording equipment, and then began developing the first television systems.

Isaac Schoenberg made a number of inventions in the field of television technology: he became the author of a transmitting tube – an emitron (Emitron), invented a method of compensating for parasitic signals from transmitting tubes. For the first time in the world history, he developed and implemented a multi-line (405-line expansion) electronic television system that operated in England until the mid-1980s. Together with his group, Isaac Schoenberg developed a new transmission tube, the super-Emitron, which had sensitivity ten times higher than its predecessor. The tube was the first to make outdoor broadcast possible in the UK.

Schoenberg's new television system was a major technical and technological achievement of that time. The merits of the inventor were recognized not only in England, but also in the USA, France, Italy and other countries. Isaac Schoenberg was awarded the prestigious Faraday Medal for achievements in telecommunications and communications. His scientific achievements were noted by the Queen of England: the inventor earned the title of “Sir”.
