This is a great saga of the exploits that great teachers do little "teaching". My guess is that poor Mr. Hoffman probably asked a lot of questions, questions that stimulated students to ask similar questions of themselves in anticipating his questions, which made them into scholars.
One should be fortunate enough to have a teacher who is this incompetent as often as possible.
I was fortunate to have studied with Hubert Butts, who not only never answered a question, but rarely, if ever, completed a sentence. His 17 Ph.D.'s will also confirm that every really good problem that came along his way for research purposes was given to a student. His attitude seemed to be that if a student solved the problem then there were two recipients of the rewards.
