Piet van Egmond (1912 – 1982) was a Dutch organist and conductor. According to tradition, Van Egmond gave his first organ recital in 1927 at the Oude Kerk in Amsterdam with a program of works by Bach. In the same year he was admitted to the Amsterdam Conservatory, where he organ studied with Cornelis de Wolf. In 1933 Van Egmond was appointed organist at the Amsterdam Concertgebouw. After World War II, he was organist successively at the Jeruzalemkerk (1952-1956), the Bachzaal Church and then the Thomaskerk in Amsterdam (1956-1967), the Gereformeerde Wilhelminakerk in Haarlem, and finally the Grote Kerk in Apeldoorn (1971-1977). He became well known for his organ improvisations on hymns and spiritual songs at the end of his organ concerts and during services.
