Sheridan Simon's Pen Name

So, I've gotten a lot of hits here looking for information about Sheridan Simon.

Sheridan Simon was a very well-known and respected Physics professor at Guilford College who was also quite enamored with science-fiction. In fact, he used to create logically plausable solar systems and planets for science-fiction authors, for a small fee. He advertised in the back of LOCUS magazine, the trade mag for the speculative fiction crowd. He designed <a target="_blank" href="http://www.fantasist.net/downloads/HoffmanQuartet.pdf">Hoffman's Quartet</a> for me in 1992, but sadly passed away in 1994. He was truly an amazing man and had a real genius for translating hard physics into very readable language that even guys like me could understand.

What's a bit more interesting, though, is that he wrote science-fiction, too. Now, for a long time his pen name was quite a mystery. In fact, the story went that even his wife didn't know the name he wrote and published under. While that makes for a good story, I don't know if it's actually true or not. In any case, a lot of folks have been through this website looking for that pen name, since I mention Dr. Simon on occasion and do rather well in the search engines. In any case, I got a wild hair to track this down the other day and I have an answer, I think. If I'm reading <a target="_blank" href="http://www.locusmag.com/index/s687.html#A16278">the entry on LocusMag.com</a> correctly, he published under the name "<a target="_blank" href="http://www.locusmag.com/index/s162.html#A3161">Yeaton Clifton</a>".

Of course, since all his work seems to have been published in now-defunct magazines, I doubt it will be very easy to find. At least you know who to look for now!
Good luck!
