Historian

A historian is a person who studies and writes about the past and is regarded as an authority on it.[1] Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. If the individual is concerned with events preceding written history, the individual is a historian of prehistory. Some historians are recognized by publications or training and experience.[2] "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere.

Herodotus (c. 484–c. 425 BC) was a Greek historian who lived in the 5th century BC and one of the earliest historians whose work survives.
