For a century the Estey Organ Company in Brattleboro, Vermont was the largest Organ (music) manufacturer in the United States. In 1852 Jacob Estey founded the company and bought out another Brattleboro manufacturing business. At its peak, the company employed more than 500 people, and sold its high-quality items as far away as Africa, Great Britain, Australia, and New Zealand. Estey built around 500,000 to 520,000 pump organs between 1846 and 1955. Estey also produced pianos, made by the Estey Piano Company in New York City.
