Sir Isaac Shoenberg (1 March 1880 – 25 January 1963) was a British electronic engineer born in Belarus who was best known for his role in the history of television.

[3] 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.

Shoenberg was born on 1 March 1880 to Jewish parents in Pinsk, Imperial Russia (now Belarus)[2] and studied mathematics and electricity at Kiev Polytechnic Institute.

[3] Shoenberg's team applied in 1932 for a patent for a new device they dubbed "the Emitron",[6] which formed the heart of the television cameras they designed for the BBC.

[2] Shoenberg's team analysed how the iconoscope (or Emitron) produces an electronic signal and concluded that its real efficiency was only about 5% of the theoretical maximum.

Schoenberg was portrayed by Leon Lissek in the 1986 TV movie The Fools on the Hill by Jack Rosenthal which dramatised the events around the first broadcasts by the BBC from Alexandra Palace in 1936.
