No one knows the place and time of my birth, but history suggests my family was aristocratic and influential in an area near Athens.

At age forty, I founded a school in Athens, called it The Academy...one of my most talented students was Aristotle.

I helped distinguish between pure and applied mathematics by enlarging the "gap" between "arithmetic" (e.g. now known as number theory) and "logistic" (e.g. now known as arithmetic).

My claim: logistics is appropriate for use in business and war by men who "must learn the art of numbers or he will not know how to array his troops," while arithmetic is appropriate for a philosopher "because he has to arise out of the sea of change and lay hold of true being."

Albert Einstein used my understanding of an immutable reality when forming objections to Niels Bohr's probabilistic picture of the physical universe.

Answer: Plato (429 - 347 BC)
