Tatiana Schlossberg, JFK’s Granddaughter and Climate Journalist, Dies at 35

By World Report Press International Desk | December 31, 2025

In a somber close to 2025, the world mourns the passing of Tatiana Schlossberg, the accomplished environmental journalist and granddaughter of former U.S. President John F. Kennedy. Tatiana died on December 30 at the age of 35, following a courageous fight against acute myeloid leukemia (AML), an aggressive blood cancer.

The Kennedy family shared the news through a poignant statement posted by the John F. Kennedy Library Foundation: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.” The message was signed by her husband George Moran, their children Edwin and Josephine, parents Caroline Kennedy and Edwin Schlossberg, and siblings Rose Schlossberg, Jack Schlossberg, and Rory.

Just over a month ago, on November 22—the anniversary of President Kennedy’s assassination—Tatiana published a deeply moving essay in The New Yorker titled “A Battle With My Blood,” where she revealed her terminal diagnosis of AML with the rare Inversion 3 mutation.

A Legacy Beyond the Kennedy Name: Advocate for the Planet

Tatiana Celia Kennedy Schlossberg, born May 5, 1990, in New York City, was the daughter of Caroline Kennedy—JFK’s only surviving child—and designer Edwin Schlossberg. Granddaughter to the legendary John F. Kennedy and Jacqueline Kennedy Onassis, she navigated the weight of her family’s history while forging a distinct path in journalism.

A Yale graduate with a master’s from Oxford University, Tatiana served as a climate reporter for The New York Times and contributed to prestigious outlets like The Atlantic, The Washington Post, and Bloomberg. Her 2019 book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, shed light on the unseen environmental consequences of everyday choices, earning widespread praise for its insightful analysis.

Married to physician George Moran since 2017, Tatiana was a loving mother to son Edwin (born 2022) and daughter Josephine (born May 2024). Tragically, her AML diagnosis emerged from routine postpartum blood tests shortly after Josephine’s birth, when elevated white blood cell counts raised alarms.

Facing Acute Myeloid Leukemia with Grace and Resolve

Tatiana’s journey involved intensive chemotherapy, a life-threatening hemorrhage, two stem cell transplants—including one from her sister Rose—and participation in cutting-edge clinical trials. Despite moments of remission, the rare mutation proved relentless.

In her essay, she expressed profound fears—that her young children might not remember her—and gratitude for her “wonderful life.” Cousin Maria Shriver described her as “valiant, strong, courageous,” highlighting Tatiana’s commitment to environmental education.

The Kennedy family, marked by generations of triumph and tragedy, endures another profound loss.

Key Symptoms of Acute Myeloid Leukemia

AML is a rapidly progressing cancer of the blood and bone marrow. Early signs often include:

• Persistent fatigue and weakness
• Frequent infections or unexplained fevers
• Unusual bruising or bleeding
• Shortness of breath
• Pale skin
• Bone or joint pain

Tatiana’s case underscored how this disease can strike suddenly, even in young, healthy individuals.

Tatiana Schlossberg’s enduring contributions to climate awareness remind us of the urgency to protect our shared planet. Her voice, though silenced too soon, continues to inspire global action.

Rest in peace, Tatiana. Condolences to the Kennedy-Schlossberg family and all who knew her.
