One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference).

What is the circumference of the Earth in miles in North South direction and East West direction?
The circumference of the Earth is approximately 24,901 miles (40,075 kilometers) when measured around the equator (East-West direction). In contrast, the circumference measured from pole to pole (North-South direction) is about 24,860 miles (40,008 kilometers). This slight difference is due to the Earth's oblate spheroid shape, which causes it to be slightly flattened at the poles.
