The beloved actress died of pneumonia, family shared
The family’s statement, issued to People and reported by Vanity Fair, set the facts and tone. The family said, “The Keaton family are very grateful for the extraordinary messages of love and support…Diane…passed away from pneumonia on October 11.” They also guided well-wishers toward service. The family added, “Any donations in her memory to a local food bank or an animal shelter would be a wonderful and much-appreciated tribute to her.”
The clarification ends days of speculation about the cause of Diane Keaton‘s death. It also reflects on Diane Keaton’s final days. She kept a low profile and stayed close to family. A friend told People her health “declined very suddenly.” Even longtime friends did not grasp the full extent of the situation. The family kept details close as they focused on her care.
Keaton’s legacy spans five decades of film and culture. She won best actress award for “Annie Hall” in 1977. She anchored landmark roles in “The Godfather” trilogy and “Reds.” Audiences embraced her later work in “Father of the Bride” and “Something’s Gotta Give.” Colleagues often praised her craft and exacting instincts. She also supported housing and animal causes, consistent with the family’s donation request.
Beyond the screen, Diane Keaton chose a private personal path. She never married, but did adopt two children, Dexter and Duke. Interviews stressed her comfort outside traditional expectations. She once said she was glad she never married. That clarity shaped her home life and career choices. The family’s statement honors that privacy and her public impact.
