Kees-Jan Waterman (1964-2018) was a Jacob Leisler Institute trustee, historian, translator, digital data expert, and recognized scholar on the collision of Indian and European peoples in North America (particularly the Hudson and Mohawk valleys) during the colonial era.
After his death, Waterman’s family donated his extensive collection of historical materials to the Institute. Comprised of more than one hundred books, personal papers (including manuscript translations and research notes), and ephemera, the Waterman Collection makes the Jacob Leisler Institute an essential repository of documentary sources on the early English period in New York.
A finding aid for the Kees-Jan Waterman Papers is in progress. Researchers can search for books in the Waterman collection here.
