So there is a heavy consesus that Arnoian, Carlsen, Adams, Keres, and Spassky are really the main guys who use 1...e5 the most?
Your original question is really too general to answer imo. If you are interested in some more specific opening variation then one could perhaps name some famous practioners but it's pretty pointless to give any specific players using 1... e5 as that list should really include most of the famous players (past and present).
Anyway, of the current players Kramnik is perhaps the main guy seeing how much his opening choices influence the other players. Aronian also plays e5 reqularily but isn't maybe quite as big opening expert as Kramnik/Anand. Carlsen plays just about anything and his main strengths lay elsewhere than in the opening although he too possibly most often chooses e5 these days. Actually, in general todays top GM's tend to have wide opening repertoires (for one thing it's more important than ever to suprise opponent due to computer assisted preparation) and are not just stuck playing few favourite lines.
e5 has always been well-respected move so you can find many other important practioners among past legends besides Spasky and Keres as well - probably majority of top players have used e5 with at least some regularity during their career.
Chessteenager, my reading of this thread is that most players rated +2700 use 1...e5 regularly, about as regularly as they use 1...c5.
If you want a list of players rated +2700 who play 1...e5, you would do well just to look at a rating list! Yes, there will be a few who don't play 1...e5, but they will be in a very small minority.
