Cathy Rosier (January 2, 1945, in Fort-de-France – May 17, 2004) was a model and actress born in Martinique, French West Indies. She died in Marrakech, Morocco, from a ruptured aorta.
Rosier was the daughter of the Martiniquais writer and painter Yva (née de Montaigne) and her husband, politician and mathematics instructor Thélus Léro.[1][2] She is perhaps best known for her role as the pianist Valerie in Jean-Pierre Melville's Le Samouraï (1967).
She also released her own musical album, entitled Cathy Banana.[3]
