Oscar-nominated actor Peter Fonda, who played a cool and introspective motorcyclist in the 1969 film "Easy Rider" that captured the spirit of the era's counterculture movement, died on Friday at age 79, his family said in a statement.

Fonda, the son of Hollywood leading man Henry Fonda and the brother of Jane Fonda, died at his home in Los Angeles on Friday morning of respiratory failure from lung cancer, the statement said.

"It is with deep sorrow that we share the news that Peter Fonda has passed away," it said, adding: "In honor of Peter, please raise a glass to freedom."

"While we mourn the loss of this sweet and gracious man, we also wish for all to celebrate his indomitable spirit and love of life," the family said.

Fonda played the wanderer Wyatt in "Easy Rider," opposite the late Dennis Hopper who co-starred as fellow biker Billy and directed the film.

In the movie, Wyatt and Billy set out on their motorbikes to discover America and have a number of misadventures, befriending an attorney played by Jack Nicholson, before meeting violent deaths.

"Easy Rider," with a script co-written by Fonda, helped usher in a period known as the "New Hollywood" era of filmmaking, which often avoided happy endings and other conventions of the Hollywood studio system.

Fonda was nominated for an Academy Award for his work on the script of "Easy Rider" and went on to act in movies and television shows at a steady pace in the decades after, achieving a second career highlight when he was nominated for the best actor Oscar for his role as a beekeeper in the 1997 drama "Ulee's Gold."

His other notable film appearances included supporting roles in the remake of the western "3:10 to Yuma" and the action-fantasy "Ghost Rider," which both came out in 2007.

Jane Fonda, who is known for her role in the 1968 film "Barbarella" and in the ongoing Netflix series "Grace and Frankie," expressed sadness at her brother's death.

"He was my sweet-hearted baby brother. The talker of the family," she said in a statement. "I have had beautiful alone time with him these last days. He went out laughing."

MOTHER'S SUICIDE

Peter Fonda, born in 1940 in New York City, lost his mother, the socialite Frances Ford Seymour, as a child when she took her own life.

Fonda later said in interviews he did not know his mother's death had been due to suicide until years later. The late Henry Fonda, who during his life had five wives, had earlier told Seymour he wanted a divorce.

Growing up, Peter Fonda attended a number of boarding schools and suffered serious injury when he accidentally shot himself with a rifle at age 11.

He admired his father, the star of films such as "The Grapes of Wrath" and "12 Angry Men," but would later describe him as emotionally distant, at least with his son.

Peter Fonda is survived by wife Margaret DeVogelaere and by his children with former wife Susan Brewer, Bridget and Justin Fonda. Both children have also worked in Hollywood.
