Updated through online information from T. Daniel Hancock. -- The New music review and church music review, Volume 9, 1909 reports "Thomas Robjohn, who with his brother, William, had been with Gray & Dorison in England, began a small organ building business in New York, during the "fifties,� and built several fine organs, notably those in South Reformed Dutch Church, New York; . . . The South Reformed Church had several novel features, viz., it was the first organ in America to have an independent pedal organ of seven stops, and the first to have a pneumatic action. During the Civil War, Dr. U.C. Burnap, then organist of the church, imported from France, a Vox Humana stop for the organ, the first of the kind used in America."
