Abstract
Many physicists all over the world noted the death of Philip Dee in April 1983 with sorrow and nostalgia. Dee’s career can be divided readily into several clearly defined periods but many will remember him first and foremost as the impressive looking scientist at the heart of matters of great moment during World War II. In those years he exerted a profound influence on many younger scientists and to the very end of his career he was held in deep respect and affection by all of those who participated in radar and other fields of scientific endeavour during the years 1939 to 1945. However, this was but one phase of the long and most fruitful career of Philip Dee as a physicist. As already mentioned it is tempting to divide Dee’s career into distinct phases but this would be to oversimplify matters and it is not at all difficult to see how each period of Dee’s career linked with the one that preceded it.
