She was one of three grandchildren of the late President John F. Kennedy. Tatiana lost her life following a tragic battle with cancer. She was the daughter of Caroline Kennedy and Edwin Schlossberg.
A Courageous Fight for Life
Schlossberg revealed her terminal diagnosis in a moving November 2025 essay. She wrote the heartfelt piece for The New Yorker magazine. In her essay, she described her difficult health journey. Doctors diagnosed her with acute myeloid leukemia in May 2024. At the time, she was only 34 years old.
She discovered the illness while hospitalized for her second child’s birth. A doctor noticed her high white blood cell count during her stay. This led to the diagnosis of a rare mutation. This specific form of leukemia usually affects much older people.

During her final trial, her doctor gave her a difficult prognosis. He estimated she might live for only one more year.

Challenging Health Policies
In her essay, Schlossberg criticized certain federal health policies. She specifically addressed her mother’s cousin, Robert F. Kennedy Jr. He currently serves as the U.S. Health and Human Services Secretary. Tatiana argued that his budget cuts could hurt cancer patients.
She noted that he cut funding for mRNA vaccine research. She believed this technology could help fight certain cancers. Her mother, Caroline, had previously urged senators to reject his confirmation. These disagreements highlighted a deep rift within the famous family.
A Legacy of Environmental Journalism
Before her illness, Tatiana built a successful career in journalism. She covered climate change for The New York Times science section. Her 2019 book received high praise from the Society of Environmental Journalists. She won the Rachel Carson Environment Book Award in 2020. Her work educated many readers about the environment and sustainability.
Family Grieves a Heartbreaking Loss
Maria Shriver honored her niece on social media Tuesday. She called Tatiana “the light, the humor, and the joy.” Shriver praised her for being a valiant and courageous fighter. Tatiana leaves behind her husband, George Moran, and two young children.
