Juliette Gréco is a French actress, chanson and cabaret singer.
Gréco became a devotee of the bohemian fashion of some intellectuals of post-war France. Duc sent her to attend acting classes given by Solange Sicard. She made her debut in the play "Victor ou les Enfants au pouvoir" in November 1946 and began to host a radio show dedicated to poetry.
Her friend Jean-Paul Sartre installed her at the Hotel La Louisiane and famously said that she had "millions of poems in her voice". She was known to many of the writers and artists working in Saint-Germain-des-Prés, such as Albert Camus, Jacques Prévert and Boris Vian, thus gaining the nickname la Muse de l'existentialisme.
Gréco spent the post-liberation years frequenting the Saint-Germain-des-Prés cafes, immersing herself in political and philosophical bohemian culture. As a regular figure at music and poetry venues like Le Tabou on Rue Dauphine, she was acquainted with Jean Cocteau, being given a role in Cocteau's film Orphée (1950). She began an affair with Miles Davis. In 1957, they decided to always be just lovers because of their careers happening in different countries and his fear of tarnishing her reputation by being in an interracial relationship. They remained lovers and friends until he died in 1991.
In 1949, she also made her debut as a cabaret singer in the parisian cabaret Le Boeuf sur le toit, performing the lyrics of a number of well-known French writers; Raymond Queneau's "Si tu t'imagines" was one of her earliest songs to become popular.
