Tatiana Schlossberg, the granddaughter of President John F. Kennedy and an acclaimed environmental journalist, died on December 30, 2025, following a battle with acute myeloid leukemia. She was 35 years old.
The family announced her death through the JFK Library Foundation.
Schlossberg was the daughter of Caroline Kennedy and Edwin Schlossberg, with siblings Rose Schlossberg and Jack Schlossberg. Her maternal grandfather, President Kennedy, was assassinated in Dallas on November 22, 1963.
Schlossberg was diagnosed with acute myeloid leukemia in May 2024, shortly after giving birth to her second child. She later learned she had a rare mutation of the disease called Inversion 3.
Following her diagnosis, Schlossberg underwent chemotherapy and received bone marrow transplants at Columbia-Presbyterian Hospital in New York. She also participated in a clinical trial for immunotherapy, exploring cutting-edge treatments in an effort to combat the aggressive disease. Despite the intensive medical interventions, she was eventually given a prognosis of one year to live.
On November 22, Schlossberg published an essay in The New Yorker detailing her cancer diagnosis and treatment journey. In the essay, she wrote candidly about the emotional toll of her illness, particularly regarding her two children: a son born in 2022 and a daughter born in May 2024.
“During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe,” Schlossberg wrote. “My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me.”
Schlossberg married George Moran in September 2017. The couple had met as undergraduates at Yale University.
Throughout her career, Schlossberg distinguished herself as an environmental journalist. She worked as a climate reporter for The New York Times, bringing attention to critical environmental issues and the impacts of climate change. Her journalism extended beyond the Times, with contributions to major publications exploring environmental themes and sustainability challenges.
In 2020, Schlossberg published the book “Inconspicuous Consumption,” which won the Rachel Carson Environment Book Award.
“Mostly, I try to live and be with them now,” she wrote in her essay. “But being in the present is harder than it sounds, so I let the memories come and go. So many of them are from my childhood that I feel as if I’m watching myself and my kids grow up at the same time. Sometimes I trick myself into thinking I’ll remember this forever, I’ll remember this when I’m dead. Obviously, I won’t. But since I don’t know what death is like and there’s no one to tell me what comes after it, I’ll keep pretending. I will keep trying to remember.”
The essay also addressed her cousin, Robert F. Kennedy Jr., and she criticized his role as Health Secretary.
Maria Shriver, a cousin and journalist, paid tribute to Schlossberg, calling her “valiant, strong, courageous.” Shriver’s statement highlighted Schlossberg’s impact as a journalist and her dedication to environmental education.
Schlossberg is survived by her husband, George Moran, their two children, her parents Caroline Kennedy and Edwin Schlossberg, and her siblings Rose and Jack Schlossberg.
