Johannes Ockeghem (born Saint-Ghislain, near Mons, Belgium about 1410; died Tours, France, 6 February 1497), was the most famous composer of the Franco-Flemish School (from around the area which is now Belgium) in the last half of the 15th century, and is often thought of as the most important composer between Dufay and Josquin des Prez. He was an excellent choirmaster and teacher. He spent most of his life working for the French royal court.
