Sir Nevile Meyrick Henderson (1882-1942), British ambassador in Berlin (1937–39) who was closely associated with Prime Minister Neville Chamberlain's policy of appeasement toward Nazi Germany. Some observers believed that he was more influential in implementing the appeasement policy than Chamberlain himself. At nine a.m. on Sunday 3 September 1939, the British Ambassador in Berlin, Sir Nevile Meyrick Henderson, went to the German Foreign Ministry building in Berlin. He had done this on many occasions in the past, but this time his message was especially ominous. Unless the German Government withdrew its troops from Poland or began that process by eleven a.m. that day, a state of war would exist between Britain and Germany. Henderson was not greeted by Hitler's inept Foreign Minister, Joachim von Ribbentrop, but by his interpreter, Paul Schmidt. The two men exchanged pleasantries and Schmidt expressed his regret about the circumstances surrounding their interview as he had 'always had the highest regard for the British ambassador'. Henderson returned to his Embassy, but no reply was ever received to the British ultimatum. Two hours later, Prime Minister Neville Chamberlain was telling the British people on the radio that Britain and Germany were at war. It was a bitter personal blow for Nevile Henderson who entitled his memoir about his time in Berlin Failure of A Mission. The war marked the end of his diplomatic career.
