Hector Dufranne was a Belgian operatic bass-baritone who enjoyed a long career that took him to opera houses throughout Europe and the United States for more than four decades. Admired for both his singing and his acting, Dufranne appeared in a large number of world premieres, most notably the role Golaud in the original Opéra-Comique production of Claude Debussy's Pelléas et Mélisande at the Salle Favart in Paris in 1902, which he went on to sing 120 times at that house. He had an excellent singing technique which maintained the quality of his voice even into the latter part of his career. His wide vocal range and rich resonant voice enabled him to sing a variety of roles which encompassed French, German, and Italian opera.

Pelléas et Mélisande is an opera in five acts with music by Claude Debussy. The French libretto was adapted from Maurice Maeterlinck's symbolist play of the same name. It premiered at the Salle Favart in Paris by the Opéra-Comique on 30 April 1902; Jean Périer was Pelléas and Mary Garden was Mélisande, conducted by André Messager, who was instrumental in getting the Opéra-Comique to stage the work. It is the only opera Debussy ever completed.
