Diane Keaton‘s family reveals Oscar winner’s cause of death

Diane Keaton died in Los Angeles on Saturday at age 79, and her family says the cause was pneumonia.

Family members of the Oscar-winning actress shared a statement with People confirming Keaton’s cause of death and saying they were “very grateful for the extraordinary messages of love and support” they had received in recent days.

The outlet first reported the news of the screen icon’s death Saturday, saying the Los Angeles Fire Department had responded to her home that morning and transported a 79-year-old woman to an area hospital. Initially, the family did not disclose the cause of death and asked for privacy as they processed their grief.

In Wednesday’s statement, Keaton’s family members said the star had a deep love for animals and was passionate about supporting the unhoused community. They encouraged people to honor her memory by donating to a food bank or animal shelter.

Keaton was known for her powerful performances in iconic pictures such as Francis Ford Coppola’s “Godfather” movies and Woody Allen’s “Annie Hall,” which earned her the 1978 Academy Award for lead actress. She was also nominated for lead actress for her roles in “Reds” (1981), “Marvin’s Room” (1996) and “Something’s Gotta Give” (2003).

Born in Los Angeles in 1946, Keaton rose to fame through her late 1960s New York stage career, earning a Tony nomination at age 25 for her role in Allen’s 1969 theatrical production of “Play It Again, Sam.”

Later in her career, she became a muse for writer-director-producer Nancy Meyers and starred in four of her movies. She was a noted trendsetter known for her fabulous on-screen outfits and, more recently, for sharing her style on Instagram, where she amassed 2.6 million followers.

Keaton’s death was widely mourned by theater, movie and fashion lovers alike.

“She was hilarious, a complete original, and completely without guile, or any of the competitiveness one would have expected from such a star,” wrote actor Bette Midler on Instagram. “What you saw was who she was.”

“Diane Keaton wasn’t just an actress: she was a force,” wrote actor Octavia Spencer on Instagram, “a woman who showed us that being yourself is the most powerful thing you can be. From Annie Hall to Something’s Gotta Give, she made every role unforgettable.”
