Tragic Loss: Tatiana Schlossberg, JFK’s Granddaughter and Environmental Journalist, Dies at 35 After Courageous Cancer Battle
In heartbreaking news on New Year’s Eve 2025, Tatiana Schlossberg, the granddaughter of President John F. Kennedy and a respected environmental journalist, has passed away at age 35 following a valiant fight against acute myeloid leukemia (AML). Her family announced the devastating loss in a poignant statement shared by the John F. Kennedy Library Foundation: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.”
Schlossberg, daughter of former U.S. Ambassador Caroline Kennedy and designer Edwin Schlossberg, publicly revealed her terminal diagnosis in a powerful November 2025 essay for The New Yorker titled “A Battle With My Blood.” Diagnosed in May 2024 shortly after giving birth to her second child, she detailed undergoing intensive chemotherapy, stem cell transplants (including one from her sister Rose), and clinical trials. Despite these efforts, the rare mutation in her AML proved aggressive, with doctors estimating less than a year to live.
A Yale and Oxford graduate, Schlossberg built a distinguished career as a climate reporter for The New York Times and contributor to outlets like The Atlantic and Vanity Fair. Her 2019 book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, explored hidden effects of everyday choices on the planet and earned acclaim for its insightful, accessible approach.
Tributes poured in from family and admirers. Cousin Maria Shriver called her “the light, the humor, the joy” and a “great journalist who used her words to educate others about the earth and how to save it.” Schlossberg’s essay also touched on family grief, noting the pain of adding “a new tragedy” to the Kennedy legacy marked by losses.
She is survived by husband George Moran, their young son Edwin and daughter Josephine, parents Caroline and Edwin, siblings Rose and Jack Schlossberg.
For American readers, Tatiana Schlossberg’s death at 35 evokes the enduring Kennedy narrative of promise cut short, while her environmental advocacy leaves a lasting call to action on climate issues. Her courage in sharing her story has inspired many facing illness.
This Tatiana Schlossberg leukemia battle and passing underscores profound loss for the Kennedy family and journalism community. As tributes continue, her work and spirit endure.
