Origin of historian
Explanation
A historian is someone who is an authority on history. Your American History textbook was written by a historian. If you've ever taken a history class, chances are it was taught by a historian — someone who is an expert on history. You don't get to be a historian overnight; most historians have studied history for years and have a Master's or Ph.D. in history. If you want an informed opinion on past elections, wars, disasters, and trends, talk to a historian or read a book by one. Historians are experts on the past.
