The Greek geographer, Strabo wrote in his work Geographica that a geographer is "the person who attempts to describe the parts of the earth".
In the twentieth century, German geographer Alfred Hettner used the term:

In the US, Richard Hartshorne worked on the notion again.
The term was popularized by Ferdinand von Richthofen.
