He won the Nobel for the invention of the CT scan. The clickbait-y part mostly concerns EMI. EMI is strange company. It started as a merger between a gramophone producer and a record company to create a vertically integrated business in the 30s. Capitalising on their expertise in sound production and broadcasting equipments they became a very important producer of radar equipments during the Second World War. And it’s this expertise in military radar technology which lead to the development of the CT scan. Meanwhile the recording part of the company merrily lived its own life and happened to produce the Beatles.
