Simone Signoret (French pronunciation: [simɔn siɲɔˈʁɛ]; 25 March 1921 – 30 September 1985) was a French cinema actress often hailed as one of France's greatest movie stars. She became the first French person to win an Academy Award, for her role in Room at the Top (1959). In her lifetime she also received a BAFTA, an Emmy, Golden Globe, Cannes Film Festival recognition and the Silver Bear for Best Actress.

Signoret was born Simone Henriette Charlotte Kaminker in Wiesbaden, Germany to André and Georgette (Signoret) Kaminker as the eldest of three children, with two younger brothers. Her father, a pioneering interpreter who worked in the League of Nations, was a French-born Jewish army officer of Polish descent, who brought the family to Neuilly-sur-Seine on the outskirts of Paris. Her mother Georgette, from whom she acquired her stage name, was a French Catholic. Signoret grew up in Paris in an intellectual atmosphere and studied the English language in school, earning a teaching certificate. She tutored English and Latin and worked part-time as a typist for a French collaborationist newspaper, Les nouveaux temps, run by Jean Luchaire.
