RIP: J. G. Ballard

Probably the best obituary for one of the greatest writers of the 20th century (no need for the science fiction adjective in there, especially as it's assumed to be a pejorative) is simply the pairing of his Assassination of JFK Considered as a Downhill Motor Race with its progenitor, Jerry's Crucifixion tale. Okay, and you need to read The Voices of Time if you haven't previously.

If you need a more traditional obit, let me recommend the rapidly updated Wikipedia article.
