Born in Béziers, Joseph Valentin Duc was a French singer, operatic forte ténor.

He is known for his repertoire at the Opéra de Paris, the Théâtre des Arènes [fr] in Béziers and world tours that took him from Monte Carlo to St. Petersburg, from Baltimore to Seville...

Son of Valentin Duc (or Duch) and Marie Fabre, originating from Tignes (Kingdom of Sardinia), he was the third in a line of eight children.

[14] After leaving the Paris Conservatoire on 25 July 1885, Valentin Duc obtained the first prize for singing in front of a jury presided by Ambroise Thomas and including Massenet, Delibes, Guiraud, etc.

[15] In the same promotion, he obtained first prize for opera in front of the same jury, supplemented by a few performers (Auguste Vitu in Le Figaro dated 31 July 1885 took the opposite opinion of his previous article).

There is no known sound recording of Valentin Duc, unlike other Biterrean tenors of this period (for example Agustarello Affre, or Léon Escalaïs).
