Franciscus ("Frans") Jozef Brüggen (30 October 1934 – 13 August 2014) was a Dutch conductor, recorder player and baroque flautist.
Born in Amsterdam, Brüggen was the last of the nine children of August Brüggen, a textile factory owner, and his wife Johanna (née Verkley), an amateur singer. He studied recorder and flute at the Amsterdam Muzieklyceum. He also studied musicology at the University of Amsterdam. In 1955, at the age of 21, he was appointed professor at the Royal Conservatory of The Hague. His reputation was initially as a recorder and Baroque flute virtuoso, and he commissioned several works for recorder including Luciano Berio's Gesti (1965). In 1972, he co-founded the avant-garde recorder ensemble Sour Cream with Kees Boeke and Walter van Hauwe.
In 1981, Brüggen co-founded with Sieuwert Verster the Orchestra of the 18th Century (Orkest van de Achttiende Eeuw). Although he did not have a formal title with the orchestra, he was its de facto chief conductor until his death. The Orchestra of the Age of Enlightenment (OAE) named Brüggen its co-principal guest conductor, in parallel with Simon Rattle, in 1992. The OAE later gave him the title of Emeritus Conductor in 2007. He was the conductor of the Radio Kamerorkest in the Netherlands from 1991 to 1994, and joint chief conductor of the orchestra, alongside Peter Eötvös, from 2001 until the dissolution of the orchestra in 2005. Brüggen conducted the final concert of the successor to the Radio Kamerorkest, the Netherlands Radio Chamber Orchestra, on 14 July 2013.
