Obituary and family statement
Tatiana Schlossberg, a 35-year-old environmental and science journalist and a granddaughter of President John F. Kennedy, died on Dec. 30, 2025, her family said in a statement shared by the John F. Kennedy Library Foundation.
“In a statement posted on social media, the family said, “Our beautiful Tatiana passed away this morning. She will always be in our hearts.””
The family statement read, "Our beautiful Tatiana passed away this morning. She will always be in our hearts."
Coverage across mainstream outlets reported the family notice and highlighted Schlossberg's status as a mother, wife and public voice on climate and science who had written candidly about her illness in a widely read New Yorker essay.
The announcement listed survivors including her husband, Dr. George Moran, their two young children, her parents Caroline Kennedy and Edwin Schlossberg, and siblings Rose and Jack.
Schlossberg illness timeline
Reporting from multiple outlets traced the onset of Schlossberg’s illness to the spring of 2024.
She was diagnosed shortly after the birth of her second child, with several outlets giving May 2024 (some specifying May 25, 2024) as the date of diagnosis.
Accounts described an aggressive acute myeloid leukemia (AML) with a rare Inversion 3 mutation.
She underwent extended hospital stays, rounds of chemotherapy, two stem‑cell or bone‑marrow transplants (including one from her sister), and participation in a CAR‑T or other clinical trial.
Doctors quoted in her New Yorker essay and in followup reporting said an experimental trial might extend her life only "for a year, maybe."
Schlossberg's career and impact
Schlossberg’s journalism and books were widely highlighted.
“Tatiana Schlossberg, a granddaughter of John F. Kennedy and an environmental journalist who wrote for The New York Times, The Atlantic and The Washington Post, has died after a battle with cancer...”
She worked as a science and environmental reporter for The New York Times and contributed to outlets including The Atlantic, Vanity Fair, and The Washington Post.
She authored the 2019 book Inconspicuous Consumption, which won environmental book awards.
Many pieces noted her education at Yale and Oxford, her newsletter, and her plans for further work on ocean conservation.
She was framed as a respected reporter who humanized complex climate and science stories even as she faced a terminal diagnosis.
Coverage of Schlossberg essay
Several outlets emphasized the emotional candor of Schlossberg's New Yorker essay, "A Battle With My Blood," quoting lines about trying to live in the present and fearing that her young children would not remember her.
Her personal writing also included political criticism: she used her platform to critique the confirmation and policies of her cousin Robert F. Kennedy Jr., warning that proposed cuts to mRNA vaccine research and other funding could harm cancer patients, a point many reports quoted or described as a family political tension.
Media coverage and reactions
Public reaction and context in coverage varied: many outlets noted tributes from friends and public figures and framed her death amid the Kennedy family’s history of public losses.
“Schlossberg — described as a wife and mother of two young children — announced a terminal diagnosis in a New Yorker essay in November... the JFK Presidential Library and Museum, which will open a condolence book Wednesday for visitors to leave messages.”
Some pieces presented medical granularities and treatment timelines (NTD, inews.zoombangla, NTD variants), while others concentrated on memorials, the family statement and calls for privacy.
Reporters across types urged respect for the family’s privacy while relaying the candid reflections Schlossberg left in her essay.
