The ancient Greek polymath Eratosthenes (c. 276 – c. 195/194 BC) is widely credited as the first person to use the word “Geography.” He coined the term from the Greek words `geo` (earth) and `graphein` (to write or describe), literally meaning "Earth writing" or "description of the Earth." Eratosthenes was also renowned for his remarkably accurate calculation of the Earth's circumference and for creating one of the earliest maps of the world, laying foundational principles for the discipline.

• Ptolemy was a later geographer who advanced cartography but did not coin the term.
• Herodotus is known as the "Father of History" and described many lands, but not the term "geography."
• Hecataeus of Miletus was an early Greek geographer, but the coinage of the term is attributed to Eratosthenes.
