Historians

Professional and amateur historians discover, collect, organize, and present information about past events. They discover this information through archeological evidence, written primary sources, verbal stories or oral histories, and other archival material. In lists of historians, historians can be grouped by order of the historical period in which they were writing, which is not necessarily the same as the period in which they specialized. Chroniclers and annalists, though they are not historians in the true sense, are also frequently included.
