François-Marie Banier

François-Marie Banier (born 27 June 1947) is a French novelist, playwright, artist, actor and photographer. His published works include Le Passé Composé (1971) and Balthazar, Fils de Famille (1985). Banier is particularly known for his photographs of celebrities and other public figures and for his friendships with members of high society. In a prominent legal case, in 2016 he was convicted of 'abuse of weakness' of the elderly billionaire Liliane Bettencourt.

Banier was born on June 27, 1947 in Paris, France. A second son, he grew up in a middle-class family in the 16th arrondissement of Paris. He has claimed he had been "completely incomprehensible to [his] parents". Although Banier was brought up as a Catholic, his Hungarian-born father (actual name: Banyaï) concealed the fact that he had converted from Judaism under the Nazi regime.

His father was an advertising executive, who beat him for disobeying “idiotic rules” and this led him to attempt suicide at the age of 15. Despite his modest background, from an early age he was a precocious and hyperactive talent, who was able to develop friendships with some of Paris' wealthiest arts patrons and artists. At the age of 16, he met Salvador Dalí, who would send his car to bring Banier to his suite at the Hotel Meurice to discuss art.
