1943: the 50th Anniversary conference

This was held in Cambridge at Newnham College and other venues in the city. It was a subdued affair given the circumstances of the ongoing war, so the Anniversary celebrations were a little muted.
One of the important elements of the event was a trio of papers from three giants of the GA's past - all former Presidents: Halford Mackinder, H J Fleure, and John Linton Myres.

They shared their views on the Development of the subject.

The resulting papers weren't actually reproduced until 1953 because of a paper shortage.
