Peter Koller provides information on the fundamental contribution of Eugen Ehrlich, a lawyer who taught in Czernowitz, to the sociology of law and points out astonishing similarities in his sociological thinking with that of Joseph A. Schumpeter. According to Koller, there are great similarities with respect to important social theoretical influences on their thinking, their chosen methodological approach, their analyses of the causes and effects of social change, and their sociopolitical attitudes. In fact, Schumpeter and Ehrlich were in close contact with each other during their time together at the University of Czernowitz through the lectures they both co-organized at the "Social Science Association."
