20th-century German economists

Ludwig Maurits Lachmann (; German: [ˈlaxman]; 1 February 1906 – 17 December 1990) was a German economist, economic theorist and important contributor to the Austrian School of Economics. Lachmann, Israel Kirzner, and Murray Rothbard were the three primary catalysts of the Austrian 'revival', beginning in 1974. He wrote on economic theory, history, and methodology, as well as on the application of Hermeneutics to economic thought, in order to interpret economic phenomena.

Walter Eucken (German: [ˈɔʏkŋ̍]; 17 January 1891 – 20 March 1950) was a German economist of the Freiburg school and father of ordoliberalism. He is closely linked with the development of the concept of "social market economy".
