The Putnam County Historian's Office (PCHO) is located in Brewster, New York, in the lower Hudson River Valley region. Our local government office preserves, interprets, and promotes the history of Putnam County dating back to its separation from Dutchess County in 1812. The Historian’s Office has been collecting historical records, maps, books, photographs, and periodicals since 1953 to support these efforts and assist researchers with genealogical, commercial, agricultural, recreational and cultural history. PCHO provides digital and on-site access to many of their records and is open for public research Monday – Wednesday, 10 am – 2 pm, by appointment.
Scope of Collection
This collection contains historic images, postcards, and documents from across Putnam County. This includes images of the factory workers of the Borden Condensed Milk factory in Brewster, gorgeous tourist photos from the late 1800s of Lake Mahopac hotels, pictures of the “Old Put” railroad line, snapshots of the Oscawana Lake community in Putnam Valley, and images from the 1895 Aqueduct Commission’s construction of Croton Watershed reservoirs, channels and dams.
