Jacques Doniol-Valcroze (15 March 1920 – 6 October 1989) was a French actor, critic, screenwriter, and director. In 1951, Doniol-Valcroze was a co-founder of the renowned film magazine Cahiers du cinéma, along with André Bazin and Joseph-Marie Lo Duca. The magazine was initially edited by Doniol-Valcroze between 1951-1957. As a critic, he championed numerous filmmakers including Orson Welles, Howard Hawks, and Nicholas Ray. In 1955, then 23-year-old François Truffaut made a short film in Doniol-Valcroze's apartment, Une Visite. Jacques's daughter Florence played a minor part in it.
