In 1845, the church purchased and installed a tracker pipe organ crafted by Henry Erben (1801–1883), one of America’s foremost organ builders of the mid‑19th century. The case of the organ is carved in the shape of a miniature Gothic chapel, echoing the church’s architecture. Its tracker action—a mechanical linkage from keys to pipe valves—offers immediate control and responsiveness superior to later pneumatic or electric systems; its tonal character recalls the Baroque-era organs for which Bach or Handel composed.
During the Civil War, federal soldiers reportedly attempted to dismantle and ship the organ to New York—but the pleas of church organist T. P. O’Neale and influential supporters saved it from removal. Over the years, modifications (including a 1929 alteration, 1969 changes, and 1984 updates) altered some features—but in 1997, the Knowlton Organ Company of NC completed a meticulous restoration aimed at faithfully returning the instrument to its original condition using Erben’s materials, tools, and methods whenever practical. This included restoring the original double-rise bellows, wind pressures (around 2‑7/8" at A=430 Hz), and removing carpeting to recover the church’s original acoustic environment.
Today, it is considered Charleston’s most historically intact working organ from the mid‑19th century.
The Erben organ remains fully playable and authentic, used for worship and occasionally featured in Charleston’s Piccolo Spoleto “L’Organo” recital series. Although concerts on this historic instrument are not offered every year, when presented it draws organ aficionados who treasure its genuine 1845 tonal voice.
This remarkable instrument not only enhances worship with its authentic sound, but serves as a living testimony to the resilience of Huguenot heritage in Charleston—saved through war, earthquake, and neglect, and lovingly restored to speak once more in its original voice.
