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

The Jupiter Hammon Project is 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 that enslaved generations of people of African descent. While enslaved at the Manor, Jupiter Hammon (1711–before 1806) wrote powerfully about the social and moral conflicts slavery raised in the newly formed United States.

Jupiter Hammon Project Roundtables

Through a series of three virtual public roundtables conducted during the late summer and early fall of 2020, Preservation Long Island brought 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 visit our Vimeo channel for content produced by Preservation Long Island for the Jupiter Hammon Project.
