The word "geography" was first used by Eratosthenes, a Greek scholar who lived from approximately 276 to 194 BC.

Eratosthenes is often credited as the "father of geography" due to his significant contributions to the field, including calculating the circumference of the Earth. He used the word "geography" in his book Geographica, which aimed to describe and map the known world.
