Guillaume Poitevin

Guillaume Poitevin (2 October 1646 – 26 January 1706) was a French Roman Catholic priest, church vocalist, serpent player, conductor, music educator, and composer.

He was trained as a singer in his youth at the Church of St. Trophime, Arles in his native city where he worked as a boy soprano.

He is best remembered for being an outstanding music teacher and director of the cathedral's choir through his role as maître de chapelle; a post he held intermittently from 1667 until his sudden death in 1706 at the age of 59.

Other musicians who were trained by him included André Campra, François Estienne, Claude Mathieu Pelegrin, Laurent Belissen, and Antoine Blanchard.
