Sir Arthur Koestler
Shocking I know, but he was knighted at some point in time, although many of the bio's on him leave this fact out of the picture. A google search with "Sir Arthur Koestler" yields 5 results.
but the Arthur Koestler archives clearly state he was a Knight.

this is not even mentioned on his wiki site. is someone trying to hide something? Info is on Arthur's Knighthood is hard to find.
