you wanted the best? well they didn't make it. so here's what you get
Oh, you said famous... then scratch "me" XD
The rest are famous, just not "science popularizer" famous
Neil degrasse Tyson
My own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.
Stephen Hawking obviously
Edward Witten (another famous theoretical physicist / mathematician)
Andrew Wiles (a mathematician, gave a proof for Fermat's Last Theorem)
To easy seeing the comments... :P
Anyway, here's some awesome people. Not all purely "scientists" per say though.
- Sir Ken Robinson
- Robert Winston
- Joy S. Reidenberg
- Michio Kaku
There's more but I forgot their names... also, a lot where already named by others.
Oh, also i'd like to add my first cousin! She is a neuro-scientist, doing work on Alzheimer among other things, she is still early in her career. But she is one of my idols ^_^

I think your requirement of 'famous' is flawed. I know many 'famous' scientists that are not in the media spotlight, but have done so much more for their respective fields of science that the primarily listed ones here. The only exception to that would be Prof. Stephen Hawking.
My 'famous' living scientists would be
Prof Stephen Hawking
Prof An Pang Tsai (person who discovered the only thermally stable binary quasicrystal, which in turn has led perfect structural solutions being calculated for this form of solid matter)
Sir Andre Geim (person who discovered a way to separate sheets of Graphene to such a degree that it is now possible to easily isolate a sheet of graphene one atom thick)
WoW PvP; Where DPS are healers, tanks are DPS, and healers are tanks!
RETH RETH RETH!
Neil deGrasse Tyson was the one i was thinking of but couldn't for the life of me remember the name >_<
Stephen Hawking (well duh)
Neil Degrasse Tyson
Michio Kaku (parallel worlds, amazing book!)
