Tatiana Schlossberg Death and Obituary – Tatiana Schlossberg, an accomplished environmental journalist and a granddaughter of former U.S. President John F. Kennedy, died on December 30, 2025, at the age of 35. Her passing has drawn widespread attention and tributes from the worlds of journalism, environmental advocacy, and American public life, where she was admired for her thoughtful reporting and principled voice.
Schlossberg died following a courageous battle with acute myeloid leukemia (AML), a rare and aggressive form of blood cancer. According to family sources, she was diagnosed in May 2024, shortly after the birth of her second child. What initially appeared to be routine postpartum medical testing revealed an abnormally high white blood cell count, prompting further evaluation and ultimately the devastating diagnosis.
Doctors later determined that Schlossberg’s leukemia involved a rare genetic abnormality known as “Inversion 3.” This mutation is typically seen in much older patients and is associated with particularly poor outcomes, making her condition terminal from the outset. Despite the grim prognosis, Schlossberg pursued every available treatment option with determination and hope.
Over the course of her illness, she underwent extensive medical interventions, including multiple rounds of chemotherapy, two bone marrow transplants, and participation in an experimental clinical trial involving CAR-T cell therapy. While these treatments initially offered brief periods of stability, the disease continued to progress. Throughout her illness, Schlossberg remained engaged with her work and her family, choosing to speak openly about her experience in an effort to bring greater awareness to cancer research and patient care.
In November 2025, just weeks before her death, Schlossberg published a deeply personal and widely shared essay in The New Yorker titled “A Battle with My Blood.” In the piece, she revealed that she had been given less than a year to live and reflected candidly on mortality, motherhood, and the limits of modern medicine. The essay also drew attention for its pointed criticism of health policies promoted by her cousin, Robert F. Kennedy Jr., underscoring her commitment to evidence-based science and public health even in her final months.
The Schlossberg family announced her passing through a statement released by the John F. Kennedy Library Foundation. “Our beautiful Tatiana passed away this morning,” the statement read. “She will always be in our hearts.” Tributes quickly followed, praising her intelligence, compassion, and courage in the face of profound adversity.
Tatiana Schlossberg is survived by her husband, George Moran, their two young children—a son and a daughter—her parents, Caroline Kennedy and Edwin Schlossberg, and her siblings, Rose and Jack. Though her life was tragically short, her legacy endures through her writing, her advocacy for environmental responsibility, and her final, powerful testimony about living with truth and dignity until the very end.
