John T. Fesperman (January 12, 1925 Charlotte, NC, US – June 2, 2001 Mitchellville, MD, US) was an American conductor, organist and author of several books on organs.
[1] Fesperman attended the University of North Carolina, cutting short his studies to serve in the U.S. Navy (1943–1946) during World War II.
In 1955 he was awarded a Fulbright scholarship to continue his studies in Amsterdam, where he met the Dutch organ-builder Dirk Andries Flentrop.
In 1965, he moved to the National Museum of History and Technology (Smithsonian), staying with that institution in various capacities for the next thirty years.
For example, he helped restore the 1855 Stevens and Jewett organ in the Armed Forces Retirement Home Protestant Chapel in Washington, DC.
