The Wirtschaftswunder (, "economic miracle"), also known as the Miracle on the Rhine, was the rapid reconstruction and development of the economies of West Germany and Austria after World War II (adopting an ordoliberalism-based social market economy). The expression referring to this phenomenon was first used by The Times in 1950. Beginning with the replacement of the Reichsmark with the Deutsche Mark in 1948 as legal tender (the Schilling was similarly re-established in Austria), a lasting era of low inflation and rapid industrial growth was overseen by the government led by West German Chancellor Konrad Adenauer and his Minister of Economics, Ludwig Erhard, who went down in history as the "father of the West German economic miracle." In Austria, efficient labor practices led to a similar period of economic growth. The era of economic growth raised West Germany and Austria from total wartime devastation to developed nations in modern Europe. At the founding of the European Common Market in 1957 West Germany's economic growth stood in contrast to the struggling conditions at the time in the United Kingdom. West Germany The fundamental reason for the quick economic recovery of West Germany can be found in the ordoliberal growth model. Germany had a skilled workforce and a high technological level in 1946, but its capital stock had largely been destroyed during and after the war. This small capital stock was compounded by the difficulty in converting the German economy to the production of civilian goods, as well as rampant monetary and regulatory problems, leading to an unusually low economic output during the first post-war years. These initial problems were overcome by the time of the currency reform of 1948, which replaced the Reichsmark with the Deutsche Mark as legal tender, halting rampant inflation. This act to strengthen the West German economy had been explicitly forbidden during the two years that JCS 1067 was in effect. JCS 1067 had directed the U.S. forces of occupation in Germany to "take no steps looking toward the economic rehabilitation of Germany". At the same time, the government, following Erhard's advice, cut taxes sharply on moderate incomes. Walter Heller, a young economist with the U.S. occupation forces who was later to become chairman of President Kennedy's Council of Economic Advisers, wrote in 1949 that to "remove the repressive effect of extremely high rates, Military Government Law No. 64 cut a wide swath across the German tax
