John Powell, physicist and company director, died on 31 December 1996, aged 73. He was born on November 4, 1923. His career followed an unusual course: from a base of research in the field of crystal technology for solid state devices in the UK at Oxford and in Canada, he had by the age of 40, and after only six years with Texas Instruments, risen from senior production engineer to become Managing Director (Northern Europe), then employing 3000 people. Three years later, he became the first non-US citizen to be appointed a Corporate Officer and Assistant Vice President of the parent company in Dallas. His subsequent working life was spent with EMI, from which he retired as a Deputy Chairman in 1979. It was in this period that he managed the development and launch world-wide of the EMI brain scanner, the revolutionary CT scanner invented by EMI’s Godfrey Hounsfield (later Sir Godfrey and a Nobel Prize-winner).
