historian

A historian is a scholar who studies and writes about the past and is regarded as an authority on it. 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. Some historians are recognized by publications or training and experience. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in German. The professionalization process spread to Japan, the Netherlands, Italy, Spain, Russia, Scandinavia, Greece, Romania, and Latin America, with each adapting the German model with local modifications.
