Forgive me writing to you after an interval of what I think must be forty-five years. Let me explain why I am writing. In the process of tidying up my room in the Marshall library, I found a diary of the Bretton Woods Conference. It was a typescript copy on foolscap paper. It was fascinating. It was obviously written by someone very much more alive and intelligent than the ordinary Treasury civil servant. By a process of elimination, I arrived at you as the almost certain author. I sent it to Donald Moggridge, who has edited the Bretton Woods volume in our Collected Writings of John Maynard Keynes. He confirmed that it was not among the Keynes papers in the King's College archive.
