Which scientist made the first accurate measurement of the earth?
Ancient writing indicates that Pythagoras postulated that the earth was round, and, about a hundred years later, Aristotle argued the same thing. Even before this, ancient peoples could see the round shadow of the earth on the moon during an eclipse. The thinking person could figure out why this would be so. It doesn't take a rocket scientist, and, though ancient peoples didn't have rockets or even aircraft to get a "bird's eye view" of things, they could observe and make conclusions quite well. Beyond these early ideations, both Pythagoras and Aristotle offered a "guestimate" of the earth's size, so it could be one of them. But it was Eratosthenes who got into it and make a nicely accurate calculation of the earth's circumference. It is possible that some other ancient investigators put forward some projections, but the written record, which suggests most clearly the who, what, when, where, and why of things olde, does not give us any other candidates.
