Tatiana Schlossberg, an environmental journalist and one of three grandchildren of former U.S. President John F. Kennedy, has died at the age of 35 following a battle with leukemia, her family announced on Tuesday.
A statement shared on social media by the John F. Kennedy Library Foundation confirmed her death, describing Schlossberg as a cherished member of the Kennedy family. “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the statement read. No further details were provided on the location or immediate cause of death.
Schlossberg, the daughter of former U.S. ambassador Caroline Kennedy and Edwin Schlossberg, revealed in a November 2025 essay published in The New Yorker that she had been diagnosed with acute myeloid leukemia last year. In the essay, titled “A Battle With My Blood,” she detailed her treatment journey, which included multiple rounds of chemotherapy, two stem cell transplants and participation in clinical trials. Doctors later informed her that treatment could extend her life for only a limited time.
She was diagnosed in May 2024 while hospitalized for the birth of her second child, after doctors noticed an unusually high white blood cell count. The leukemia involved a rare mutation typically seen in older patients.
Tributes poured in following the announcement of her death. Maria Shriver, a niece of President Kennedy, described Schlossberg as “the light, the humor, the joy” of the family and praised her work as a journalist committed to educating the public about environmental protection.
Schlossberg worked as a reporter for The New York Times Science section, where she covered climate change and environmental issues. She was also the author of Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have, a 2019 book that won the Society of Environmental Journalists’ Rachel Carson Environment Book Award in 2020.
In her final essay, Schlossberg also raised concerns about U.S. health policy, criticizing cuts to medical research funding and warning of their potential impact on cancer patients. She wrote candidly about her fears of leaving behind her young children and the emotional toll her illness took on her family.
Born into one of America’s most prominent political families, Schlossberg’s life and work reflected a commitment to public service through journalism rather than politics. Family members and colleagues remembered her as intellectually sharp, compassionate and deeply devoted to environmental causes.
Her death marks another profound loss for the Kennedy family, which has endured a long history of tragedy alongside public service. Schlossberg is survived by her husband, George Moran, their two children, her parents and her siblings.
