Clip from the first ever piece of film footage shot in stereo, ‘Trains At Hayes’, produced by prolific engineer and innovator Alan Dower Blumlein, the inventor of stereo. This film was shot from a window in the EMI offices in Hayes, West London in 1935 onto the local train station to test this new technology which would revolutionise audio recording. While working at EMI Blumlein would develop many ground-breaking and hugely influential technologies including electrical television and airborne radar as well as stereo.
