Executive summary: Stereophonic recording

Electrical engineer Alan Blumlein was attempting to improve cinema sound systems by having sound emanate from more than one speaker, when in 1931 he devised a system for embedding two separate sound channels into a single record groove. Calling it binaural sound -- now known as stereo -- he made several experimental recordings and films, but his employer, EMI, had little interest in stereo, and instead focused Blumlein's attention on television. With Isaac Shoenberg, he invented 405-line monochrome TV broadcasting, the first TV format widely used, which was the standard in the UK from 1936 to the mid-1960s. Earlier, while working at Columbia Graphophone, he invented a wax cutting machine for making better gramophone masters, and a moving coil microphone. He was testing an improved targeting system for bombing when he was killed in a plane wreck in 1942, about fifteen years before stereophonic recordings became popular.
