Sir Isaac Shoenberg was a British electronic engineer born in Belarus who was best known for his role in the history of television. He was the head of the EMI research team that developed the 405-line, the first fully electronic television system to be used in regular broadcasting when it was introduced with the BBC Television Service in 1936. It was later adopted by other TV organizations around the world.
As the head of research at EMI, Schoenberg was Alan Blumlein's supervisor when Blumlein invented stereophonic sound in 1931. Schoenberg was awarded the IET Faraday Medal by the British Institution of Electrical Engineers in 1954 and was knighted by Queen Elizabeth II in 1962.
