Louis Hector Berlioz was a 19th century French composer. While patrolling the Romulan Neutral Zone aboard the USS Enterprise-E in 2373, Captain Jean-Luc Picard listened to Vallon sonore from the opera Les Troyens by Berlioz. Commander Riker entered his quarters and mistook it for Bizet. (Star Trek: First Contact) In a vision of USS Voyager as Gre'thor experienced by B'Elanna Torres in 2376, The Doctor informed her that he would be performing an aria from Berlioz's The Damnation of Faust on the holodeck.
