Chamberlain, (Arthur) Neville 1869 - 1940. British Conservative politician. Son of Joseph Chamberlain. He was prime minister 1937-40; his policy of appeasement toward the fascist dictators Mussolini and Hitler (with whom he concluded the Munich Agreement 1938) failed to prevent the outbreak of World War II. He resigned 1940 following the defeat of the British forces in Norway. Younger son of Joseph Chamberlain and half-brother of Austen Chamberlain, he was born in Birmingham, of which he was lord mayor 1915. He was minister of health 1923 and 1924-29 and worked at slum clearance. In 1931 he was chancellor of the Exchequer in the national government, and in 1937 succeeded Baldwin as prime minister. Trying to close the old Anglo-Irish feud, he agreed to return to Eire those ports that had been occupied by the navy. He also attempted to appease the demands of the European dictators, particularly Mussolini. In 1938 he went to Munich and negotiated with Hitler the settlement of the Czechoslovak question. He was ecstatically received on his return, and claimed that the Munich Agreement brought "peace in our time". Within a year, however, Britain was at war with Germany.
