The Culper Spy Letter: A New Discovery at the Long Island Museum

In August 2020 the Long Island Museum discovered an uncatalogued Culper Spy Ring letter in its collections. Acquired by the museum in December 1951, the handwritten double-sided letter measures 9 3/16” x 7 5/8”, is dated November 8, 1779, and is from Benjamin Tallmadge (using his alias, John Bolton) to Robert Townsend (alias, Samuel Culper Jr.).

The Long Island Museum is proud to offer its latest online publication: Long Road to Freedom: Surviving Slavery on Long Island.

Based on the 2019 exhibition of the same name, the publication written by LIM’s curator Jonathan M. Olly, Ph.D., focuses on the experiences of people of color from the 17th to 19th centuries. The five-chapter publication explores: how slavery operated, how African Americans resisted bondage, navigated the era of emancipation, and built communities in the decades after slavery, from Brooklyn to the Hamptons.
