Environmental journalist Tatiana Schlossberg, who was a granddaughter of former U.S. President John F. Kennedy, has passed away at the age of 35. Schlossberg, the daughter of Caroline Kennedy and Edwin Schlossberg, publicly disclosed her terminal cancer diagnosis in a November 2025 article in The New Yorker. Her family confirmed her death in a statement posted on social media by the John F. Kennedy Library Foundation on Tuesday.
Schlossberg was diagnosed with acute myeloid leukemia in May 2024 at 34 years old, following the birth of her second child. In her essay titled “A Battle With My Blood,” she detailed her experiences with chemotherapy, stem cell transplants, and participation in clinical trials. She mentioned her doctor’s prognosis that he could potentially extend her life by a year. Additionally, Schlossberg criticized certain healthcare policies advocated by her mother’s relative, U.S. Health and Human Services Secretary Robert F. Kennedy Jr., expressing concerns about their impact on cancer patients like herself.
Prior to her passing, Schlossberg worked as a journalist covering climate change and environmental issues for the science section of The New York Times. Her book, “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have,” received the Rachel Carson environment book award from the Society of Environmental Journalists in 2020.
In her poignant essay, Schlossberg expressed her fears about her young children not remembering her and lamented the life she would be missing with her husband, George Moran. Despite her family’s efforts to conceal their sadness, she indicated that she could sense their pain every day.
Caroline Kennedy, Schlossberg’s mother, had endured significant tragedies in her own life, including the assassinations of her father, President John F. Kennedy, and her uncle, Robert F. Kennedy. These familial losses were further compounded by the death of Caroline’s brother, John F. Kennedy Jr., in a plane crash in 1999 alongside his wife and her sister.
Tatiana Schlossberg’s legacy as a dedicated environmental journalist and her courageous battle with leukemia have left a lasting impact on those who knew her and the broader community.
