Apparently Douglas Adams is the only ever comedy science fiction writer:
Had he not died 12 years ago, Douglas Adams would have been recovering today from celebrating his 61st birthday. Yesterday, Google produced a doodle in his memory. And the Guardian published an interesting piece which declared that Adams remains the king of comedy SF, before going on to argue that he was unique, pretty much the only writer in that genre. Take a bow Mr Adams; you’re top of a league of one.
Funny that the Guardian article didn't say anything of the sort - it even cites some other SF comic writers! The point was rather that Adams broke through to a much wider audience, something that other SF comedians largely failed to do. As ever The Spectator parades its SF ignorance.
And the grandpa of SF comic writers - and writer of "And then there were none" - Eric Frank Russell needs a bit more of a hearing:
“You seem to fit the part all right. Your technical record is first-class. Your disciplinary record stinks to high heaven.' He eyed his listener blank faced. 'Two charges of refusing to obey a lawful order. Four for insolence and insubordination. One for parading with your cap on back to front. What on earth made you do that?'
I had a bad attack of what-the-hell, sir,' explained Leeming.”
That's from 'Next of Kin" (originally published as "The Space Willies" - which I could explain but that would be too much of a spoiler) - a real laugh out loud book. Go read!
