Paul Sweezy was an assistant of Schumpeter. Their friendship and intellectual distance are such that the word pupil sounds off-key. As he wrote to his brother Al, though interested in the Austrian economist’s theories, he did not feel any particular influence. The personal relationship, however, was quite strong, as if he was the substitute for a missing child. There was a memorable debate between them, of which a record remains, thanks to Paul Samuelson’s ‘memoir’, which appeared in Newsweek, 13 April 1970, and the materials made available by John Bellamy Foster in the Monthly Review, May 2011.
