NEW YORK — Tatiana Schlossberg, granddaughter of the late President John F. Kennedy and a respected environmental journalist, has died at the age of 35 after a courageous battle with a rare and aggressive form of leukemia, her family announced Tuesday. Her passing marks yet another heartbreaking chapter in a family long shadowed by loss and public tragedy. 
Schlossberg, the daughter of former U.S. Ambassador Caroline Kennedy and designer Edwin Schlossberg, passed away on December 30. The John F. Kennedy Presidential Library Foundation shared a statement on social media saying, “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” signed by her husband, George Moran, their two young children, and her immediate family.
Diagnosed in May 2024 with acute myeloid leukemia just days after giving birth to her second child, Schlossberg publicly revealed her terminal illness in a poignant essay for The New Yorker in November 2025. In the essay, she detailed her shock at the diagnosis and the grueling treatments she endured, including chemotherapy, stem cell transplants, and experimental therapies. Despite her bravery, the disease proved relentless.
In her writing, Schlossberg spoke not as a public figure but as a mother facing the unimaginable fear of leaving her young children behind. She expressed the heartbreak of knowing her son and daughter might grow up with only fragmented memories of her.
An accomplished journalist, Schlossberg reported on climate and environmental issues for major publications including The New York Times. She was also the author of a well‑received book on environmental impact. Her death deprives the journalism community of a passionate voice and her family of a cherished daughter, sister, wife, and mother.
The Kennedy family has endured generations of high‑profile tragedies, from the assassinations of President Kennedy and his brother Robert F. Kennedy to the deaths of other family members in accidents. Schlossberg’s untimely passing at a young age adds fresh sorrow to that poignant legacy.
Public tributes have poured in from colleagues, friends, and readers who admired her courage both as a journalist and as a person confronting immense adversity with honesty and grace
