Alan Blumlein developed the first stereo sound recording technologies, patenting his inventions in 1931 and subsequently testing them with both audio and video. Some of his ideas were twenty years ahead of their time, but his employers at EMI did not perceive the commercial potential of stereo, and Blumlein was moved onto other projects.
After working on the new technology of televsion for EMI, Blumlein was drafted onto ground-scanning radar for the British government during the Second World War. While working on the hush-hush H2S project in 1942, Blumlein was fatally injured when a Halifax bomber testing his equipment over the Herefordshire countryside caught fire and crashed.
