The Radio Filharmonisch Orkest (Radio Philharmonic Orchestra; Netherlands Radio Philharmonic Orchestra; Dutch abbreviation = RFO) is a Dutch radio orchestra, based in Hilversum. The RFO performs under the aegis of the Muziekcentrum van de Omroep (Broadcasting Music Centre; NMBC), an umbrella organization bringing together the music departments of the various broadcasting associations affiliated to Nederlandse Publieke Omroep (Dutch Public Broadcasting).
The RFO performs on NPO Radio 4 and gives public concerts in Amsterdam and Utrecht. It has also served as the orchestra for productions at De Nederlandse Opera. The RFO's programmes are decided by the above-mentioned Muziekcentrum, rather than directly by the orchestra's management and chief conductor. The current manager of the RFO is Wouter den Hond.
Albert van Raalte founded the orchestra in 1945 and served as its first Chief Conductor. Past Chief Conductors have included Paul van Kempen, Bernard Haitink, Jean Fournet, Willem van Otterloo, Hans Vonk, and Sergiu Comissiona. Edo de Waart was Chief Conductor of the RFO from 1989 to 2004 and is now its conductor laureate. Jaap van Zweden was Chief Conductor and Artistic Director of the RFO from 2005 to 2012, and now has the title of honorair gastdirigent (honorary guest conductor, or principal guest conductor). In August 2010, the RFO announced the appointment of Markus Stenz as its 8th Chief Conductor, effective from the start of the 2012-2013 season, with an initial contract of three years.
In October 2010, the coalition Dutch government announced plans for complete defunding of the Muziekcentrum van de Omroep by the year 2012, with the potential threat of the dissolution of the RFO. After protests, the Dutch Minister of Education, Culture and Sciences Marja van Bijsterveldt announced in December 2010 a partial restoration of funds to the NMBC at a level of €12 million-14 million. In December 2012, the RFO named Bernard Haitink as its patron, following his advocacy for the orchestra in the wake of the proposed defunding.
