Claude Bertrand was a French actor and voice artist, born Claude Ernest Bertrand on March 24, 1919, in Gréasque, France. He passed away on December 14, 1986, in Montpellier at the age of 67. While he had a career in film and television, he is best remembered for his extensive and influential work in dubbing. Passionate about theater from a young age, he was admitted to the Conservatoire national d’art dramatique de Paris. He began his performance career in 1946 doing background work at the Théâtre du Vieux-Colombier before making his film debut in 1948.

Bertrand became a major figure in French dubbing during the 1960s and 1970s. He was known as the regular French voice for several major Hollywood and international actors. He provided the French voice for Roger Moore, most notably in the James Bond film series from 1973 to 1985, as well as for other actors including Bud Spencer, Burt Lancaster, John Wayne, and Charles Bronson. His ability to adapt his vocal performance was notable, using a deep, heavy voice for actors like Bud Spencer and a softer, gentlemanly English tone for Roger Moore.

In the world of animation and anime, Claude Bertrand voiced numerous iconic characters. He is particularly remembered for his work on Disney productions, providing the French voice of Baloo in The Jungle Book, Thomas O'Malley in The Aristocats, and Little John in Robin Hood. He was also the voice of Captain Haddock in the animated Tintin films The Temple of the Sun and The Lake of Sharks. In Japanese anime series that were adapted for French audiences, he voiced Banta in Goldorak and Doctor Zero in Albator, le corsaire de l'espace (known as Space Pirate Captain Harlock). He also contributed voices to other animated series, including characters in Scooby-Doo and as Le Teigneux in Il était une fois... l'Homme.

Beyond dubbing, Bertrand appeared in French television, including episodes of the series Les Cinq Dernières Minutes and performances in the theater broadcast program Au théâtre ce soir. In 1979, he reduced his professional activities but continued to travel to Paris for dubbing work. His legacy is defined by his prolific and celebrated voice work, making him a familiar and beloved presence in French popular culture through his roles in both international live-action films and animated classics.
