I found this amusing series of letters in a collection of pre-war Bartlett correspondence in UCL Records, between Charles Douie, the then secretary to UCL and H. Claughton, an unknown.

They concern the temporary relocation of the Atelier (5th year Architecture studio) to Malet Place, but in amongst the serious business of organising planning permission these two appear to have taken the time to have a friendly squabble.

While trying to find out some more about the dry wit that was Charles Douie, I came across this pencil sketch in the UCL Art Museum, along with one of his wife. It seems he was enough of a University College institution to earn his own portrait.
