BOSTON — Tatiana Schlossberg, an environmental journalist and a granddaughter of President John F. Kennedy, died Tuesday at 35, her family said in a statement shared by the John F. Kennedy Library Foundation, Dec. 30, 2025.
In a November essay for The New Yorker, Tatiana Schlossberg wrote that she had been diagnosed in May 2024 with acute myeloid leukemia marked by a rare mutation, after doctors noticed abnormal blood counts while she was in the hospital following the birth of her second child.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the family statement said. The announcement did not disclose where she died or provide additional medical details.
Tatiana Schlossberg’s work made climate change feel personal
Before her illness, Tatiana Schlossberg built a reputation for reporting that translated sprawling environmental problems into the routines of everyday life — what people wear, eat, stream and throw away. She covered climate change and the environment for The New York Times’ science desk and later expanded her work into long-form writing and books, according to The Associated Press.
Her 2019 book, “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have,” traced the hidden footprint behind modern convenience, from technology and fashion to food and fuel. In a 2019 Vogue interview, Tatiana Schlossberg described how the ecological costs of consumption are often pushed out of sight until they accumulate into visible damage.
In a 2020 conversation with Climate One, she argued that personal choices matter most when they lead to collective action, saying “it’s almost impossible to make an impact free choice in our current system.” Her book later received the Society of Environmental Journalists’ Rachel Carson Environment Book Award.
A widely read final essay and a family’s private grief
Tatiana Schlossberg was the middle child of Caroline Kennedy and Edwin Schlossberg and one of three Kennedy grandchildren known to the public through family ceremonies and civic events. In her New Yorker essay, she described months of chemotherapy, stem cell transplants and clinical trials while raising a toddler and caring for a newborn — a collision of motherhood and mortality that made her writing widely shared.
She also wrote about watching national health debates from the vantage point of hospital rooms and infusion chairs. In the essay, she criticized moves by her cousin, Health and Human Services Secretary Robert F. Kennedy Jr., that she said threatened medical research funding and could harm patients like her, while praising the clinicians and researchers fighting to extend life for people with blood cancers.
Reporting on her death, Reuters said the family announcement was posted through the John F. Kennedy Presidential Library and Museum’s social media channels. The news prompted tributes that highlighted her warmth, humor and insistence that hard truths should be stated plainly.
Tatiana Schlossberg is survived by her husband, George Moran, their two young children and her parents and siblings. In her final essay, she returned again and again to what she feared her children might not remember — and to the same reporting instinct that defined her career: pay attention to what is easy to overlook and act while there is still time.
