It's a sad day indeed. He'll be missed.
A quick anecdote showing the sort of person Ray Bradbury was:
In 1952, Al Feldstein of EC Comics adapted two Bradbury short stories without permission, combining them into a single comic short. Many an author or publisher, then and now, upon learning that this sort of thing had been done, would immediately release the lawyers, as they'd be legally entitled to. Instead, Bradbury wrote Feldstein and EC publisher Bill Gaines a letter praising their adaptation of his work, while noting wryly that he'd "inadvertently" not yet received his payment. Feldstein and Gaines, taking the hint, sent him a cheque and contacted him to negotiate terms for future adaptations of his stories. They would go on, with Bradbury's full endorsement, to adapt some two dozen of his stories, in titles such as Weird Science and Weird Fantasy.
