One of my grandfathers was working for Metrovick [1] at the start of the 30s. His boss suggested that he go get a PhD and hopefully there would be more work when he had finished. He chose to go to Aachen [2] and learned German well enough to get his Dr Ing. Back at Metrovick he worked on high power radio transmitters, one he designed for the Rugby Radio Station [3] became the basis of the one for the Chain Home system and he was in charge of production of them by Metrovick. Because he spoke German he was a member of the Allied Control Commission immediately after the war and went round all the German electronics companies to find out what they had been doing. He found that he knew all the senior people who had been working on competing technology from when they had been students together.
