John Greer: A Life Remembered

John Greer was a civilian laborer who lived and worked at Fort Jefferson during the early 1860s. He died on November 5, 1861, though the exact circumstances of his death are unknown.

Greer was buried in what is now known as the Fort Jefferson Post Cemetery, located on a nearby island that has since become submerged. His grave was identified during an archeological survey and is marked by a large slab of gray stone, carved in the shape of a headstone and inscribed with his name and date of death. The stone itself is made of the same material used in the construction of Fort Jefferson.

While much of the history of Fort Jefferson focuses on soldiers and prisoners, John Greer’s story represents the many civilian workers who helped support daily life at the remote fort. His burial site offers a rare and personal connection to those individuals, whose contributions are often less visible in the historical record.

Research into Greer’s life and the lives of others buried at the site is ongoing, helping to expand our understanding of the diverse community that once lived and worked at Fort Jefferson.
