The Royal Conservatory of Brussels is a historic conservatory in Brussels, Belgium. Starting its activities in 1813, it received its official name in 1832. Providing performing music and drama courses, the institution became renowned partly because of the international reputation of its successive directors such as François-Joseph Fétis, François-Auguste Gevaert, Edgar Tinel, Joseph Jongen and Marcel Poot, but more because it has been attended by many of the top musicians, actors and artists in Belgium such as Arthur Grumiaux, José Van Dam, Sigiswald Kuijken, Josse De Pauw, Luk van Mello and Luk De Konink. Adolphe Sax, inventor of the saxophone, also studied at the Brussels Conservatory.

François-Joseph Fétis was a Belgian musicologist, critic, teacher and composer. He was among the most influential music intellectuals in continental Europe. His enormous compilation of biographical data in the Biographie universelle des musiciens remains an important source of information today.
