Sir Austen Joseph Chamberlain (1863-1937) was a British Conservative politician, elder son of Joseph Chamberlain.
As foreign secretary 1924-1929 he negotiated the Pact of Locamo (settling Germany's West frontiers), for which he won the Nobel Peace Prize in 1925, and signed the Kellogg-Briand pact (renouncing war) in 1928.
He was elected to Parliament in 1892 as a Liberal-Unionist, and after holding several minor posts was chancellor of the Exchequer 1903-1906. During World War I he was secretary of state for India 1915-1917 and member of the war cabinet in 1918.
He was chancellor of the Exchequer 1919-1921 and Lord Privy Seal 1921-1922, but failed to secure the leadership of the party in 1922, as many Conservatives resented the part he had taken in the Irish settlement of 1921. He was foreign secretary in the Baldwin government 1924-1929.
Austen Chamberlain was a British statesman, recipient of the Nobel Peace Prize.
