The world has lost a gifted voice and a remarkable human being. Tatiana Schlossberg—environmental journalist, author, and granddaughter of President John F. Kennedy—passed away on December 30, 2025, at just 35 years old after a courageous battle with acute myeloid leukemia (AML), a rare and aggressive blood cancer.
Her family shared the heartbreaking news through the John F. Kennedy Library Foundation, writing: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.” The statement was signed by her husband, George Moran; their children, Edwin and Josephine; her parents, Caroline Kennedy and Edwin Schlossberg; and her siblings, Jack and Rose Schlossberg, along with Rose’s spouse, Rory.
Tatiana’s death comes only weeks after she publicly revealed her terminal diagnosis in a deeply personal and moving essay for The New Yorker, titled “A Battle With My Blood,” published in November 2025. In the essay, she described discovering her illness shortly after giving birth to her daughter, Josephine, in May 2024. What followed was an exhausting and relentless fight that included chemotherapy, multiple stem cell transplants—one donated by her sister Rose—and experimental clinical trials. Despite her resilience and determination, the cancer, driven by a rare mutation known as Inversion 3, could not be overcome.
Born Tatiana Celia Kennedy Schlossberg on May 5, 1990, in New York City, she was the middle child of Caroline Kennedy—the former U.S. ambassador and only surviving child of President John F. Kennedy and Jacqueline Kennedy Onassis—and designer Edwin Schlossberg. Educated at Yale University and later earning a master’s degree from Oxford, Tatiana forged her own path, becoming a respected journalist with a fierce commitment to environmental reporting.
She wrote for The New York Times and contributed to The Atlantic, The Washington Post, and other leading publications. Her 2019 book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, was widely praised for illuminating the hidden environmental costs of everyday consumer habits and for challenging readers to rethink their relationship with the planet.
In 2017, Tatiana married her Yale classmate, physician George Moran, in a ceremony at the Kennedy family compound on Martha’s Vineyard. Together, they built a life rooted in love and purpose, welcoming their son Edwin in 2022 and their daughter Josephine in 2024. In her final writings, Tatiana reflected tenderly on motherhood, expressing a heartbreaking fear that her children might not remember her—yet her words revealed a woman deeply present, fiercely loving, and determined to give meaning to every remaining moment.
Tributes poured in following the news of her passing. Her cousin Maria Shriver remembered Tatiana as “valiant, strong, [and] courageous,” praising her as “a great journalist” who used her voice to educate others about the Earth and how to protect it.
In a family long marked by public service and profound loss, Tatiana Schlossberg’s death feels especially poignant—another luminous spirit taken far too soon. Yet her legacy endures: in her powerful writing, her unwavering advocacy for the environment, and the love she leaves behind for her young family.
Rest in peace, Tatiana. You fought with grace and courage, and your voice will continue to inspire efforts to protect the world you cared for so deeply.
Our deepest thoughts and condolences are with the Kennedy and Schlossberg families during this heartbreaking time.
