She carried one of history's most iconic names, but she forged her own path through the power of the written word. Tatiana Schlossberg, the granddaughter of late President John F. Kennedy and a respected environmental journalist, has died at the age of 35 following a battle with cancer. Her family confirmed she passed away on Tuesday, December 30, 2025.

The family announced her passing via the JFK Library Foundation's official Instagram, stating, "Our beautiful Tatiana passed away this morning. She will always be in our hearts." Schlossberg was not just a member of American royalty; she was a tenacious science and climate reporter for The New York Times. Her 2019 book, "Inconspicuous Consumption: The Environmental Impact You Don't Know You Have," earned critical acclaim for making complex climate issues accessible to the public.

A Courageous Battle with Leukemia

Schlossberg's diagnosis came at a bittersweet moment. In May 2024, following the birth of her second child, doctors detected an unusually high white blood cell count. She was diagnosed with acute myeloid leukemia (AML), a condition more commonly seen in older patients or 9/11 first responders. In a poignant essay published in The New Yorker last month, she wrote movingly about her clinical trials and the heartbreaking fear that her children wouldn't remember her.

Holding Power to Account

Even from her hospital bed, Schlossberg remained a committed journalist. She was notably critical of her relative, Robert F. Kennedy Jr., who currently serves as Health Secretary in President Donald Trump's cabinet. Schlossberg questioned his lack of medical background and expressed deep concern over policies that curtailed vaccine access and slashed medical research spending. "I watched... as Bobby, in the face of logic and common sense, was confirmed," she wrote, prioritizing scientific integrity over family ties.
