Alain Delon was born in Sceaux, Seine (now Hauts-de-Seine), Île-de-France, an upscale suburb of Paris. His parents, Édith (née Arnold; 1911–1995) and Fabien Delon (1904–1977), divorced when Delon was four. Both remarried and as a result, Delon has a half-sister and two half-brothers. His paternal grandmother was Corsican, from Prunelli-di-Fiumorbo. When his parents divorced, Delon was sent to live with foster parents; after the foster parents died, Delon's parents took shared custody of him, but the arrangement proved unsatisfactory. He attended a Catholic boarding school, the first of several schools from which he was expelled because of unruly behavior. Delon left school at 14, and worked for a brief time at his stepfather's butcher shop. He enlisted in the French Navy three years later, aged 17, and during 1953–1954 he served as a fusilier marin in the First Indochina War. He has said that, of his four years of military service, he spent 11 months in a military jail for being "undisciplined".
