The Second Japanese Army Cipher Conference 1944
The second Japanese Army Communications Conference (JAC) held in Arlington Hall in Virginia, in March 1944 was significant not just because it codified sharing arrangements which would be carried through into what eventually became the UKUSA Five Eyes partnership, but because so many of the architects of post-war signals intelligence came together: William Friedman and Solomon Kullback from the US; John Tiltman and "Jumbo" Travis from the UK; Ed Drake from Canada.

I'm not concerned today with the weighty affairs discussed at the 2nd JAC, but with the social event which accompanied it. A copy of the menu for the Conference dinner gives an insight into the culinary and entertainment treats offered to delegates.
I have been to many conferences and have enjoyed many conference dinners, but I have never been served green turtle soup, with or without sherry, and I cannot remember cauliflower balls au gratin ever gracing the table. As for the entertainment: was "GI Fun" a stand-up comedian? What did the exclusively male and mainly military audience make of the "Jitterbug Couple" and their swing quartet?
We will probably never know, unless somebody's private diary surfaces, but it is interesting to note that somebody thought that "The Power of Concentration" would be an appropriate variety turn at the greatest gathering of Five Eyes cryptologists during the Second World War.
