Did you know that one of the earliest published African American authors was born on Long Island in 1711 and that he survived four generations of enslavement? His name was Jupiter Hammon. 

Join Preservation Long Island for the Jupiter Hammon Project, a major initiative to develop a more relevant and equitable interpretation of Joseph Lloyd Manor, one of Preservation Long Island’s historic houses and a site of Black enslavement. While enslaved at the Manor, Jupiter Hammon (1711–ca.1806) wrote powerfully about the social and moral conflicts slavery raised in the newly formed United States.

Through a series of three virtual public roundtables conducted during the late summer and early fall of 2020, the Jupiter Hammon Project will bring together renowned scholars and professionals with local residents, descendant communities, and other stakeholders to explore the legacy of slavery on Long Island and the life of Jupiter Hammon. Please join the conversation! Links to event details and registration below.
