Genre lists: the best science fiction authors and series

All right. I've written about my crime fiction list and my fantasy list; here, rounding out the genres (at least those in which I'm interested), is my chronological list of the authors and series in science fiction that I have read or aim to read. Far from exhaustive, and not aiming to be "completist." I want to read the best. What should I add to it? [NB: The list has now been expanded with suggestions.]
