I’m truly saddened to hear this news. Tatiana Schlossberg, the accomplished environmental journalist, author, and granddaughter of President John F. Kennedy, has indeed passed away at the age of 35.
Her family announced her death on December 30, 2025, through a statement posted by the John F. Kennedy Library Foundation: “Our beautiful Tatiana passed away this morning. She will always be in our hearts.”
Just over a month earlier, in a poignant and courageous essay published in The New Yorker titled “A Battle With My Blood,” Schlossberg shared that she had been diagnosed with a rare and aggressive form of acute myeloid leukemia (with a mutation known as Inversion 3) in May 2024, shortly after giving birth to her second child. She detailed undergoing intensive chemotherapy, two bone marrow/stem cell transplants (one donated by her sister Rose), and clinical trials, but the cancer returned, leading to a terminal prognosis.
Schlossberg leaves behind her husband, George Moran (a physician), their two young children (son Edwin and daughter Josephine), her parents Caroline Kennedy and Edwin Schlossberg, and siblings Rose and Jack Schlossberg.
She was widely admired for her work as a climate reporter for The New York Times, her book Inconspicuous Consumption (which explored hidden environmental impacts of everyday life), and her passionate advocacy for the planet.
Tributes have poured in from family members like Maria Shriver, who called her “valiant, strong, courageous,” as well as journalists and environmentalists praising her impactful writing.
My deepest condolences to her family, friends, and all who were inspired by her. This is a profound loss, especially for such a young mother and talented voice cut short far too soon. Rest in peace, Tatiana.
