Drawing on Henry Spiegel, I argued that --  
"Fairly general agreement defines the sociological  
characteristics of a school of economic thought. Henry W.  
Spiegel, for instance, notes that a school consists of 'a  
recognized leader, a closely knit group of followers to  
exalt and spread the doctrines of the master, and a  
periodical to help in their dissemination.'   
  
Can one attribute the lack of a Schumpeterian school or even a nucleus of it to 
such semi-biographical factors? I remember Bob Heilbroner, who was his student at Harvard,
saying that Schumpeter never promoted his work among his students and assiduously
refrained from assigning his works as readings. But I also remember hearing/reading that
Schumpeter was unhappy that he did not leave a 'school' behind.
 
At least in his own actions, he would not be guilty of "The one thing that cannot be
forgiven a great scholar is the school he leaves behind him", quoting Tom Easterbrook via
Robin Neill.
