Tatiana Schlossberg, environmental journalist and granddaughter of President John F. Kennedy, has died at 35 after a battle with acute myeloid leukemia. She bravely revealed her terminal diagnosis and criticized a relative's policies in a final essay.
Tatiana Schlossberg, 35, an environmental journalist and granddaughter of the late President John F. Kennedy, has passed away after being diagnosed with acute myeloid leukemia last year. The daughter of Caroline Kennedy and Edwin Schlossberg, she shared her terminal cancer diagnosis in a November 2025 essay for The New Yorker, titled 'A Battle With My Blood.' Her death was announced by the John F. Kennedy Library Foundation. Maria Shriver, a niece of JFK, paid tribute to Schlossberg on social media, calling her 'the light, the humor, the joy' and praising her as a journalist who educated others on environmental issues. Schlossberg was diagnosed with acute myeloid leukemia, which included a rare mutation, in May 2024 at the age of 34, after doctors detected a high white blood cell count during the birth of her second child. Her treatment involved rounds of chemotherapy, two stem cell transplants, and participation in clinical trials. In her essay, she recounted a doctor's grim prognosis during a recent trial, stating he could keep her alive 'for a year, maybe.' Schlossberg also used her platform to criticize policies advocated by her mother’s cousin, Health and Human Services Secretary Robert F. Kennedy Jr., specifically his backing of cuts to mRNA vaccine research, which she argued could harm cancer patients like herself. Her mother had previously urged senators to reject his confirmation.
