I was really tempted to do some kind of subject line with a punch line of “once a knight is enough,” but I manfully resisted the temptation. (The fact that I wasn’t able to come up with something on short notice that really worked well had nothing to do with it!)
Anyway, there was a story dated November 2, 2011, in the Greenwich, Connecticut Greenwich Time about Peter von Braun, who is running for election to the Board of Education there. There is, apparently, some controversy being stirred up by his opponents about the fact that he calls himself a knight.
What the controversy really boils down to is that Mr. von Braun has not been knighted per se, but is a Knight of Grace of the Order of St. John, a chivalric order headed by Queen Elizabeth II. So he can’t add “Sir” as a title to his name, but, yes, technically he is a knight.
If you’d like to read the full story of the controversy, including what David White, Somerset Herald of the College of Arms in London had to say to inquiries about von Braun's knighthood, it can be found on-line at: http://www.greenwichtime.com/news/article/He-s-no-Beatle-but-yes-von-Braun-is-a-knight-2249330.php
