Alfred Duff Cooper (1890–1954) was a statesman, diplomat, and historian. He was a decorated officer during the First World War and entered Parliament in 1923. He remained a politician until 1938, when he resigned in protest at Britain's appeasement policy toward Nazi Germany. Called back to office by Winston Churchill in 1940, his wartime career culminated in his appointment as Ambassador to France. Shortly before his death he was made 1st Viscount Norwich. He was married to Lady Diana Cooper, the famed society debutant, actress, and writer. Operation Heartbreak is his only novel.
