The historical school of economics was an approach to academic economics and to public administration that emerged in the 19th century in Germany, and held sway there until well into the 20th century. The professors involved compiled massive economic histories of Germany and Europe. Numerous Americans were their students. The school was opposed by theoretical economists. Prominent leaders included Gustav von Schmoller (1838–1917), and Max Weber (1864–1920) in Germany, and Joseph Schumpeter (1883–1950) in Austria and the United States.
