Environmental journalist Tatiana Schlossberg, granddaughter of the late President John F. Kennedy, has died. She was 35.
Schlossberg, the daughter of Kennedy’s daughter, Caroline Kennedy and Edwin Schlossberg, revealed that she had terminal cancer in a November 2025 essay in The New Yorker. Her family released a statement about her death, which was posted on the John F. Kennedy Library Foundation’s social media.
“Our beautiful Tatiana passed away this morning. She will be in our hearts forever,” the statement read. She did not release the cause of death or say where she died.
Schlossberg was diagnosed with acute myeloid leukemia in May 2024 at the age of 34. After the birth of her second child, her doctor noticed a high white blood cell count. It turned out to be acute myeloid leukemia with a rare mutation mostly seen in older people.
In an essay “Fight With My Blood”, Schlossberg said he went through rounds of chemotherapy and two stem cell transplants and participated in clinical trials. During the last trial, she wrote, her doctor told her he “could keep me alive for maybe a year.”
Schlossberg also criticized the policies promoted by her mother’s cousin, the Secretary of Health and Human Services Robert F. Kennedy Jr.she says in the essay that the policies she supported could harm cancer patients like her. Her mother urged senators to reject his confirmation.
“As I spent more and more of my life in the care of doctors, nurses and researchers trying to improve the lives of others, I watched as Bobby cut nearly half a billion dollars into research into mRNA vaccines, a technology that could be used against certain cancers,” the essay reads.
Schlossberg worked as a climate change and environment reporter for Science at The New York Times. Her 2019 book “Conspicuous Consumption: The Environmental Impact You Don’t Know You Have” won the 2020 Rachel Carson Environment Book Award from the Society of Environmental Journalists.
Schlossberg wrote in an essay for The New Yorker that she was afraid her daughter and son would not remember her. She felt cheated and sad that she would no longer be able to live the “wonderful life” she had with her husband, George Moran. While her parents and siblings, Rose and Jack, tried to hide their pain from her, she said she felt it every day.
“All my life I’ve tried to be good, to be a good student and a good sister and a good daughter and to protect my mother and never upset her or make her angry,” she said. “Now I’ve added a new tragedy to her life, to our family’s life, and there’s nothing I can do to stop it.”
