PARIS — French actor Alain Delon, who captured the hearts of millions of film enthusiasts with his performances as a murderer, hoodlum, or hitman during his post-war heyday, has passed away, as announced by his three children on Sunday. He was 88 years old.

Delon's health had been declining since suffering a stroke in 2019, and he rarely left his estate in Douchy, located in France's Val de Loire region.

President Emmanuel Macron praised him as a giant of French culture.

"Alain Delon has played legendary roles and made the world dream. Lending his unforgettable face to shake up our lives. Melancholic, popular, secretive, he was more than a star: he was a French monument," he posted on X.

With striking blue eyes, Delon was sometimes referred to as the "French Frank Sinatra" for his handsome looks, a comparison Delon disliked. Unlike Sinatra, who always denied connections with the Mafia, Delon openly acknowledged his shady pals in the underworld.

In a 1970 interview with the New York Times, Delon was asked about such acquaintances, one of whom was among the last "Godfathers" of the underworld in the Mediterranean port of Marseille.

"Most of them, the gangsters I know ... were my friends before I became an actor," he said. "I don't worry about what a friend does. Each is responsible for his own act. It doesn't matter what he does."

Stardom

Delon shot to fame in two films by Italian director Luchino Visconti, "Rocco and His Brothers" in 1960 and "The Leopard" in 1963.

He starred alongside Jean Gabin in Henri Verneuil's 1963 film "Melodie en Sous-Sol" ("Any Number Can Win") and was a major hit in Jean-Pierre Melville's 1967 "Le Samourai" ("The Godson"). The role of a philosophical contract killer involved minimal dialogue and frequent solo scenes, and Delon shone.

Delon became a star in France and was idolized by men and women in Japan, but never made it as big in Hollywood despite performing with American cinema giants, including Burt Lancaster when the Frenchman played apprentice-hitman Scorpio in the eponymous 1973 film.

In the 1970 film "Borsalino," he starred with fellow French actor Jean-Paul Belmondo, playing gangsters who come to blows in an unforgettable, stylized fight over a woman.

Crowning moments also included 1969 erotic thriller "La Piscine" ("The Swimming Pool"), where Delon paired up with real-life lover Romy Schneider, in a sultry French Riviera saga of jealousy and seduction.

Delon's standout film in the 1970s — a decade during which he and Belmondo were staples of the French box office — was the 1976 Joseph Losey film "Monsieur Klein" in which he plays an art dealer in occupied Paris during World War Two who is taken for a Jewish fugitive of the same name.

Troubled Man

Born just outside Paris on November 8, 1935, Delon was put in foster care aged four after his parents divorced.

He ran away from home at least once and was expelled several times from boarding schools before joining the Marines at 17 and serving in then-French-ruled Indochina. There too he got into trouble over a stolen jeep.

Back in France in the mid-50s, he worked as a porter at Paris wholesale food market, Les Halles, and spent time in the red-light Pigalle district before migrating to the cafes of the bohemian St. Germain des Pres area.

There he met French actor Jean-Claude Brialy, who took him to the Cannes Film Festival, where he attracted the attention of an American talent scout who arranged a screen test.

He made his film debut in 1957 in "Quand la femme s'en mele" ("Send a Woman When the Devil Fails").

Sulfurous Friends

Delon was a businessman as well as an actor, leveraging his looks to sell branded cosmetics and dabbling in race horses with old underworld friends. He invested in a race
