Esther Elizabeth Fleet (1809-c.1870) was organist of St. Botolph's Church, Bishopsgate, London, where she presided over a three-manual Byfield organ. The organ has happily been restored following damage by a terrorist bomb in 1993. By the way, St. Botolph is the saint after whom Boston is named. Boston = Botolph's-town.
Her Voluntary for the Organ in C major, an Introduction and Fugue, was published in 1826, and was one of two published works by Miss Fleet (later Mrs. Cope). It is a rare and fine example of a an early nineteenth-century voluntary written by a woman composer. It is also remarkable for its early use of metronome markings, the metronome only having been invented by Johann Mäzel in Germany ten years previously.
