A Rich History: From Military Base to Research Hub
Early History and Military Significance
The history of Plum Island dates back to the 17th century, when it was inhabited by the Pequot tribe, who referred to it as “Manittuwond.” It was purchased by European settlers in 1659, and over the next few centuries, the island changed ownership several times. In 1899, the U.S. government acquired the island for military use, leading to the construction of Fort Terry in 1897. Fort Terry played an essential role during both World Wars as part of the U.S. coastal defense system. However, following its deactivation in 1949, the island’s function shifted from military defense to scientific research.
The Plum Island Animal Disease Center (PIADC)
In 1952, the U.S. government established the Plum Island Animal Disease Center (PIADC), a specialized research facility dedicated to the study of animal diseases like foot-and-mouth disease (FMD). This facility has been vital in protecting U.S. livestock from foreign diseases that could devastate the agricultural industry. As of 2026, the PIADC is scheduled to relocate to Kansas, marking the end of a significant era in the island’s history.
