Ludwig Wilhelm Erhard (4 February 1897 – 5 May 1977) was a German politician affiliated with the CDU and Chancellor of the Federal Republic of Germany (West Germany) from 1963 until 1966. He is often famed for leading German postwar economic reforms and economic recovery ("Wirtschaftswunder", German for "economic miracle"), in his role as Minister of Economics under Chancellor Konrad Adenauer in 1949, prior to his own ascension to the Chancellorship in 1963. As Chancellor, however, his fame rapidly declined. Erhard resigned his Chancellorship on 1 December 1966.
