   That is quite arguable.   
   Much of mathematics wouldn't exist   
   without (what was once) new input from physics.   
   Many a luminary, Von Neumann for example,   
   has said that mathematics will go stale   
   without regular fresh input from the natural sciences,   
   bringing new needs.

   Why discredit him by calling him 'a mathematical physicist'?   
   He was a theoretical physicist,   
      
   Jan   
      
   --   
   Paul Adrien Maurice Dirac 8 August 1902 – 20 October 1984) was a British   
   -theoretical physicist- who is considered to be one of the founders of   
   quantum mechanics.       (first line of your ref., [emp. jjl])
