The Annual Theory Meetings ("Christmas Meetings") started in 1961 and have been held every year since (with the possible exception of two years), previously at the Rutherford Appleton Laboratory and more recently at Durham. Gordon Moorhouse and David Morgan have written a brief history of the early meetings.
