Galbraith in the Rhetoric Department?

Galbraith wrote an article in The Atlantic giving writing tips (don't procrastinate, don't try to be funny, don't get drunk), and says in the beginning:

"Six or seven years ago, when I was spending a couple of terms at Trinity College, Cambridge, I received a proposal of more than usual interest from the University of California. It was that I resign from Harvard and accept a chair in English. More precisely, it was to be the chair in rhetoric; they assured me that rhetoric was a traditional and not, as one would naturally suppose, a pejorative title. My task would be to hold seminars with the young on what I had learned about writing in general and on technical matters in particular."
