Tatiana Schlossberg, JFK Granddaughter, Dies at 35

Tatiana Schlossberg — environmental journalist, author, and granddaughter of President John F. Kennedy — died on December 30, 2025, at the age of 35 after battling acute myeloid leukemia, her family announced through the John F. Kennedy Library Foundation. Schlossberg was the daughter of Caroline Kennedy and Edwin Schlossberg and was married to Dr. George Moran; the couple had two young children together.

Schlossberg’s passing brought an outpouring of grief from friends, family, and public figures who praised her intellect, courage, and compassion. Known for her thoughtful writing on climate change, conservation, and the environment, she was widely admired both for her professional work and her open reflections on life, family, and illness.

Tatiana Schlossberg: Journalism, Advocacy, and Writing

A Yale University graduate who also held a master’s degree from Oxford University, Schlossberg worked as an environmental and science reporter for major publications, including The New York Times, and contributed to outlets such as The Atlantic, The Washington Post, Vanity Fair, and Bloomberg News. Her 2019 book Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have won acclaim from critics and her peers, earning the Rachel Carson Environment Book Award in 2020.

Her work often focused on helping readers understand the hidden environmental impacts of everyday choices, blending rigorous reporting with a compassionate, accessible style.

A Painful Diagnosis and Courageous Fight

Shortly after the birth of her daughter in May 2024, doctors discovered an abnormally high white blood cell count, which led to a diagnosis of acute myeloid leukemia — a rare, aggressive blood cancer typically seen in older adults. In a poignant essay for The New Yorker published in November 2025, Schlossberg shared the emotional and physical toll of her illness. She described her disbelief at the diagnosis, the intensity of her treatment — including chemotherapy, bone marrow transplants, and clinical trials — and her profound love for her family as she faced her mortality.

In the essay titled “A Battle With My Blood,” Schlossberg also critiqued her cousin Robert F. Kennedy Jr., then serving as U.S. Secretary of Health and Human Services, for policies she felt were undermining cancer research and public health efforts — a bold, personal argument tied to her firsthand experiences with treatment access and medical science.

She wrote candidly about the difficulty of accepting that her children — a son and daughter — might grow up with only memories and photographs of her, and how she tried to fill her remaining time with love, presence, and meaningful connection.

Family, Legacy, and Tributes

Schlossberg’s death added another chapter to the Kennedy family’s history of public service and personal tragedy, evoking sympathy from across the political and cultural spectrum. Her brother, Jack Schlossberg, and sister, Rose Schlossberg, both shared memories of her warmth, dedication, and brilliance. Public figures, including former California First Lady Maria Shriver, joined friends and admirers in mourning her loss as a “brave and compassionate voice.”

In announcing her death, the JFK Library Foundation wrote, “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” a message signed by Tatiana’s close family members.
