Tatiana Schlossberg, the granddaughter of President John F. Kennedy and daughter of Caroline Kennedy, has passed away at age 35 after a battle with acute myeloid leukemia. The news was shared via the JFK Library Foundation's social media, confirming her death on December 30, 2025. Schlossberg had publicly revealed her terminal diagnosis just weeks earlier in a poignant New Yorker essay.
Oh, the Kennedy curse strikes again, doesn't it? Tatiana Schlossberg, that sharp environmental journalist who kept her famous family life low-key, left us way too soon. At 35, she fought like a champ against acute myeloid leukemia with a rare Inversion 3 mutation, diagnosed right after giving birth to her daughter in May 2024. 'I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew,' she wrote in her November 22, 2025, New Yorker essay 'A Battle With My Blood,' as reported by Hollywood Life.
The essay spilled raw tea on her shock—routine bloodwork post-delivery showed sky-high white cells, leading to chemo, a bone-marrow transplant, and experimental CAR-T therapy. Doctors gave her maybe a year, per the piece. Married to physician George Moran since 2017 (vows at the family's Martha’s Vineyard spot), they share son Edwin, born 2022, and daughter Josephine, May 2024. 'My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,' Tatiana shared, highlighting the gut-punch to her young family.
A Yale history grad, she penned for The New York Times, The Atlantic, Washington Post, and more, dropping her 2019 book Inconspicuous Consumption on sneaky environmental impacts. The JFK Library Foundation broke the news on Instagram: 'Our beautiful Tatiana passed away this morning. She will always be in our hearts,' signed by George, Edwin, and Josephine Moran; Ed, Caroline, Jack, Rose, and Rory. Her brother Jack's recent Congress run in New York adds another layer of legacy drama. And in a shady aside, she called cousin Robert F. Kennedy Jr. an 'embarrassment' for slashing cancer research funds amid her fight.
Tatiana's words linger: 'When you are dying... you start remembering everything.' The Kennedys have seen assassinations and crashes before—JFK in 1963, uncle John Jr. in 1999—but this quiet loss hits different. So, in a family full of icons, will Tatiana's voice on climate and life echo loudest? 💔
