Well, they didn't actually measure the earth, they made an educated (?) guess at the distance. Just reading Bill Bryson's 'A Short History of Nearly Everything'. Two Frenchmen are sent to South America to measure the angle between two points so that a calculation can be made of the Earth's diameter. They return home nine and a half years later, having not talked to each other for eight years because of a disagreement, to find a different survey crew has gone to Scandinavia and already returned with the relevant information! At least they tried.
