Born in 1927, Gréco was imprisoned by the Nazis during World War Two, but afterwards began performing in cellar clubs and cafes.
Dressed in black, she became a muse to philosophers and writers including Jean-Paul Sartre and Albert Camus.
She only stopped performing aged 89 after a farewell tour.
Gréco was also a celebrated actor, working with some of cinema's greats, such as Jean Cocteau and Ingrid Bergman, Orson Welles and Ava Gardner.
