Isabelle Yasmina Adjani (born 27 June 1955) is a French film actress and singer. She is the only actress or actor in history to win five César Awards; she won Best Actress for Possession (1981), One Deadly Summer (1983), Camille Claudel (1988), La Reine Margot (1994), and Skirt Day (2009). She was made a Chevalier of the Legion of Honour in 2010, and a Commander of the Order of Arts and Letters in 2014.
Adjani’s performance as Adèle Hugo in the 1975 film The Story of Adele H. earned her the first of two nominations for the Academy Award for Best Actress. Her second nomination—for Camille Claudel—made her the first French actress to receive two nominations for foreign-language films. She won Best Actress at the 1981 Cannes Film Festival for her performances in Possession and Quartet, and, later, she won the Silver Bear for Best Actress at the 1989 Berlin Film Festival for Camille Claudel. Her other notable film performances include The Tenant (1976), Nosferatu the Vampyre (1979), Subway (1985), Diabolique (1996), and French Women (2014).
