This chapter sharpens the history of economics by examining how statistics, and a quantitative methodology more generally, took root in Russian economics. K. F. Hermann played an important role, revealing how actors with particular institutional capacities, skills, and capital can influence the operating logics of fields and discourses. Both British and German approaches were available, and ultimately, the German approach won out, in no small part, because of Hermann and his colleagues. Statistics was not the inevitable core of economics methodology: Hermann had to make the case that statistics not only provided important data for the state, as well as economists, to have a true sense of the state of Russian economy and society; it was also a true form of “science.”
