Council, recognising that the Institute did not have an open award specifically for theoretical physics, decided in 1985 to introduce a new medal and prize to be named after P A M Dirac an Honorary Fellow, who had died the previous year.
The award shall be made annually for outstanding contributions to theoretical (including mathematical and computational) physics. The medal shall be silver gilt and shall be accompanied by a prize of £1000 and a certificate.
Medallist for 2005 : John Ellis
