Jean Michaud was a French actor and voice actor, born on July 12, 1921, in Tunis and passing away on June 2, 2001, in Paris. His career spanned from the early 1950s until 1999, during which he was active in film, television, and scriptwriting, though he became particularly renowned for his voice work.

Within the realm of animation voice acting, Michaud contributed his voice to several series and films. One of his noted roles was as the second voice of Papa Moomin in the Japanese-Finnish-Dutch animated series Les Moomins, which corresponds to the titles Tanoshii Moomin Ikka: Bōken Nikki and Tanoshii Moomin Ikka mentioned in the query. His other animation voice roles included the character Eole in the Franco-Japanese series Ulysse 31, the Grand Inca in the 1969 animated film Tintin et le Temple du Soleil, and various characters in series such as Métal Hurlant and Papyrus.

While his work in animation was part of his broader career, Michaud was most widely recognized in French popular culture for dubbing roles in live-action productions. He was the regular French voice of actor Lorne Greene, most notably as the patriarch Ben Cartwright in the long-running series Bonanza and as Commander Adama in the original Battlestar Galactica series. He also succeeded actor Michel Gatineau as the French voice of Inspector Derrick, portrayed by Horst Tappert, beginning in 1989. Other significant dubbing credits included providing the French voice for actor Richard Gere's character in the film Pretty Woman.
