On topic, I'll try to list some - because I'm afraid my list could very quickly grow too long.
Some of the SF authors I am very fond of hark back to the ones I read young, most likely in Russian translations, at least initially. Those would include the Strugatsky brothers, Stanislaw Lem, Ray Bradbury, Kurt Vonnegut Jr, Robert Sheckley, Clifford Simak and Arthur C. Clarke. Roger Zelazny was also heavily and pretty well translated into Russian, but the only book of his that has really shined for me was Lord of the Light and that one I read lately in English.
These would later be followed by William Gibson (and Bruce Sterling to a lesser extent - Bruce is a brilliant writer and even more brilliant thinker, but for some reason his books, while excellent, didn't stick with me as deeply, same with Rudy Rucker), Ursula Le Guin, Frank Herbert, and Orson Scott Card (far from loving ALL of his stuff, but I think Ender's Game should be taught in school and the whole Ender series is deeply brilliant). Neal Stephenson I highly value, but more for the technical insight and scrupulous attention to detail than for any emotionally rich remembrances. Iain M. Banks has been a late addition to my repertoire but definitely up in the top 10or maybe 15, for The Culture series. I also highly enjoy China Mieville's works, New Crobuzon series in particular with Perdido Street Station as the peak of it.
