Rochester & Monroe County Historians

The Local History & Genealogy Division is home to the Office of the Rochester and Monroe County Historian and the Monroe County Historical Archives. Under New York State law (New York Arts & Cultural Affairs Law § 57.07 and 57.09 and New York County Law § 400), every county, city, town, and village is required to appoint a historian to document, preserve, interpret, and share their community’s history.

“Each local government historian shall promote the establishment and improvement of programs for the management and preservation of local government records with enduring value for historical or other research;  encourage the coordinated collection and preservation of nongovernmental historical records by libraries, historical societies, and other repositories;  and carry out and actively encourage research in such records in order to add to the knowledge, understanding and appreciation of the community’s history.”


The historian’s duties fall into four categories: 1) research and writing, 2) teaching and public presentations, 3) historic preservation (documents, artifacts, and buildings), and 4) organization, advocacy, and tourism promotion. The County Historian is additionally tasked with supervising the activities of town and village historians.
