Susan - you can put a name on the post From line even as a guest, as I demonstrate here; it's the preferred etiquette so we can follow who is posting, even guests. It doesn't even have to be your real name as long as it's consistent. (Of course as a guest anyone could pretend to be you. But before I was a member I was a guest for some time, posting consistently as MCP - my initials - that's why they're in my member name, to link my old guest posts with my member ones)

Your professor may not be famous, but if we knew the name we could look him/her up and see what other work he/she did and make up our own minds. That's the advantage of having a consistent name - you can follow someone's body of work.

The fame/lack of fame of your professors doesn't tell us anything. I had some very famous professors of maths and computer science (the two disciplines I trained in) and some not so famous. It didn't mean I was taught anything better by the more famous ones than by the less famous. (At least one very famous professor of complex mathematics was an awful teacher!). You have no evidence that we will take the fame of your authority into account when you proffer your aphorism. However since your professor appears to be have been Thomas Huxley, I would say that he's famous enough, though you must to be a lot older than other members of this forum. I therefore bow to your venerable wisdom.
