It depends on how you look at it.
Best insertions of workable science?
Or stories that roped more people in and helped grow the genre?

John W Campbell and Robert Silverberg were primarily editors, but for me they were instant buy writers.


Alice Mary (Andre) Norton didn't write stories explaining how the technologies might work, but her mostly juvenile and young adult works were widely read and drew people in.

A lot of books I read in the sixties were one offs, and from the writing styles I suspected at the time that they were pseudonyms for just a few authors. To answer your question thoroughly I would have to be able to remember all the titles and then research who the actual writers were.

I suspect that for me it would be like researching nineteen seventies American Rock Music and finding out that two thirds of the drummers on your favorite albums were really the same session musician.
