Tatiana Schlossberg

American environmental journalist and author, also noted as a daughter of Caroline Kennedy, a U.S. Ambassador to Japan, and a granddaughter of John F. Kennedy, the 35th U.S. president. A reporter for The New York Times covering climate change, Schlossberg also wrote for The Atlantic and other publications. She authored the book Inconspicuous Consumption: The Environmental Impact You Don't Know You Have (2019).

Schlossberg had two siblings, Rose and Jack. She attended Yale University and graduated in 2012. She went on to receive a Master's in American History from the University of Oxford in 2014.

In 2011, a man pleaded guilty to stalking Schlossberg and her aggravated harassment. He received 60 days in jail and three years' probation, along with a protection order barring him from contacting anyone in the Schlossberg or Kennedy families.

On 9 September 2017, Schlossberg married her college boyfriend George Moran in Martha's Vineyard. The couple had a son Edwin born in 2022 and daughter Josephine in 2024.

In 2024, immediately after the birth of her daughter, Schlossberg was diagnosed with acute myeloid leukaemia. On 22 November 2025, Schlossberg revealed in a New Yorker essay that her leukaemia had developed "a rare mutation called Inversion 3," which made it a terminal form of the disease. A bone marrow transplant, chemotherapy, and a clinical trial of CAR-T cell therapy were unable to slow the progression of the leukaemia, and her doctors informed her that she had one year to live.

Tatiana Schlossberg died on 30 December 2025 at the age of 35. Her family announced her death on the John F. Kennedy Library Foundation's Instagram account.
