Opera singer Elisabeth Schwarzkopf, who set the Desert Island Discs all-comers record for self-referentiality by choosing eight records of her own performances, has an intellectual soul-mate in Michael Intriligator of the University of California at Los Angeles. He cited 22 articles in an article of his in a 1990 issue of Defence Economics. Of these, some 22 were written, in part or whole, by one M. Intriligator.
