At this point in time, I'd have to hand it to either Aristotle or the founders of the largest current religions. Aristotle if you care about intellectual currents(that guy founded all manner of disciplines, and advanced a fair few more, as well as being the intellectual underpinning of c. 1000 years in the west, and 4 or 5 hundred in Islamic regions). If popular/cultural stuff is more important to you, religion founders take the cake.
Now, another question: who do you think will be, among reasonably contemporary figures(say now living or up to 100 years dead), the most influential person as we go forward in history?
In any case, I suspect the Rivest, Shamir, Adleman trio will make the cut. In my pessimistic prediction for the future, Mark Stefik will be the other most influential. In my optimistic prediction, Richard Stallman will be.
