A geographer is a physical scientist, social scientist or humanist whose area of study is
geography, the study of Earth's
natural environment and human society, including how society and nature interacts. The Greek prefix "geo" means "earth" and the Greek suffix, "graphy," meaning "description," so a geographer is someone who studies the earth. The word "geography" is a
Middle French word that is believed to have been first used in 1540.
Although geographers are historically known as people who make
maps, map making is actually the field of study of
cartography, a subset of geography. Geographers do not study only the details of the natural environment or human society, but they also study the reciprocal relationship between these two. For example, they study how the natural environment contributes to human society and how human society affects the natural environment.
In particular, physical geographers study the natural environment while human geographers study human society and culture. Some geographers are practitioners of GIS (
geographic information system) and are often employed by local, state, and federal government agencies as well as in the private sector by environmental and engineering firms.
The paintings by
Johannes Vermeer titled The Geographer and The Astronomer are both thought to represent the growing influence and rise in prominence of scientific enquiry in Europe at the time of their painting in 1668–69.
