Just a stab at this point (I'll dig more later) and my guess is Sir Ronald Adam. He was GOC Northern Command in 1940-41 then Adjutant General 1941-46.

Yes, I think that you are right about Sir Ronald Adam - who was quite the unsung hero of the war too. He took on the military establishment in an effort to improve the quality of British Officers and his War Office Selection Board is still largely the same process as his vision created in 1941. That is some achievement. Regards FdeP

I've just reviewed Roger Broad's biography of Adam ('The Radical General') for the National Army Museum, and indeed he was acutely aware that this was a citizen Army of temporary soldiers for the duration, not a recruitment pool for a post-war Army - and shook up selection procedures to make sure that skills fitted need (even if the individual didn't know it). There was a music hall joke in 1940.... "They asked me what I did in civvy street... I said I was a plumber, so they asked me to weld some pipes. I did; they said they were the best they'd ever seen.... so they made me a cook" Churchill tried to sack him three times; on the last attempt Alanbrooke said that he would remain CIGS for as long as Adam was AG. Point taken. Adam's professional and personal friendship with Brooke was critical... Mind you, one proposal he made really upset the Army; that the soldiers of a battalion should be allowed to nominate candidates from amongst the NCOs for officer training. How.... how.... socialist! Bernard Paget, no slouch as a trainer himself and friendly towards Adam personally, described him as 'a menace to morale.'
Thanks for all the replies. I agree its Sir Ronald Adam. I found the link to the National Portrait museum, about half an hour after I'd posted the thread, going down the possible GOC Northern Command candidates, and was unable to delete the thread. Thanks again
