Ludwig Lachmann (1906–1990) was a German-born member of the Austrian School of economics. He studied at the London School of Economics in the 1930s, taught at the University of Wiwatersrand in South Africa, and wrote seminal material on Austrian capital theory.
Ludwig von Mises: "Marx and Engels never tried to refute their opponents with argument. They insulted, ridiculed, derided, slandered, and traduced them, and in the use of these methods their followers are not less expert. Their polemic is directed never against the argument of the opponent, but always against his person." - Socialism
