Any competition between guys who go by one-word names is going to be tight, and this one's no exception. Our beloved cover boy Einstein has a pretty solid claim to being the 20th century's greatest scientist on the merits of his explanation of Brownian motion and formulation of the theory of relativity alone. Plato, for his part, is one of the key figures in the development in philosophy. Not just a student of Socrates and a teacher of Aristotle, Plato's dialogues and formulation of Platonic realism have been confusing and enlightening scholars for centuries now. (Plus, he had some serious chops as a wrestler.) Who's coming out on top here, the man who helped us harness the atom or the man who taught us to think a little differently about caves?
