Lord Lothian played a leading part in defeating Hitler during the short period of his embassy at Washington.
It was he who persuaded Churchill to write the historic letter to Roosevelt which for the first time gave the Americans an unequivocal statement of Britain's depleted military strength.
At a daringly timed conference in Washington , Lothian delivered a similar message to the American public.
Listen to this speech which was to be his last during his final visit to America.
The RAF Oulton Museum is an integral part of the Blickling Estate.
During World War II Blickling Hall and its surrounding buildings and land became billets for aircrew from nearby RAF Oulton.
This museum remembers those men and women who served as part of Bomber Command squadrons and risked their lives carrying out raids over Germany.
From great works of art by Gainsborough to the ordinary cotton underpants of a Midlands grocer, details of over 700,000 objects in the care of the National Trust are now online. Find out more about Blickling's important collection here, which includes magnificent tapestries, portraits by Gainsborough and Mytens and a fine view of Chelsea by Canaletto.
