Let me quote what Schumpeter said on the Austrian or Viennese School, his own (?) School: "The close cultural relations that existed between the Austro-Hungarian monarchy and Germany did not prevent the emergence in Austria of a scientific situation in our field that differed completely from the German one. This was largely due to two personal facts: to the fact that Carl Menger was a leader of quite unusual force; and to the fact that he found two disciples, Bohm-Bawerk and Wieser, who were his intellectual equals and who completed Menger's success." (History of Economic Analysis, New York, Oxford University Press, 1986, p. 844) Here obviously, he had a leader-follower relationship in mind. Whether this remains to be a sound analytical tool for historians of economic thought today, or whether the concept "school" plays an important role in the History of Economic Analysis by Schumpeter, these are different stories. Another quite intriguing question from the historical point of view is when people began to talk about schools. Perhaps one has to turn to early examples of the usage, "Classical School" or "English Classical School of Economics". Cheers Yukihiro Ikeda
