The Kennedy Light Dimmed: The Heartbreaking Passing of Tatiana Schlossberg at 35 and the Courageous Final Message She Left for the World

Tatiana Schlossberg, an author, environmental journalist and granddaughter of former President John F. Kennedy, has died at 35, just over a month after revealing that she had been diagnosed with terminal cancer.

Her family shared the news of her death on Dec. 30 on the Instagram account for the John F. Kennedy Library Foundation

“Our beautiful Tatiana passed away this morning,” they wrote. “She will always be in our hearts.”

The message was signed “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”

Schlossberg announced in an essay for The New Yorker on Nov. 22 that she had been diagnosed with acute myeloid leukemia, which she described as “terminal.”

Schlossberg, the daughter of Caroline Kennedy and Edwin Schlossberg, wrote that she learned about her diagnosis in May 2024 after giving birth to her second child.

Acute myeloid leukemia is an aggressive and rare cancer that affects the bone marrow and blood and is mostly seen in people 60 and older, according to Cleveland Clinic.

Tatiana Schlossberg wrote that she had undergone a stem cell transplant from her sister and was in remission before the cancer was detected again.

“During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe,” she wrote at the time.

Schlossberg is the older sister of 2026 congressional candidate Jack Schlossberg, 32, and the younger sister of Rose Schlossberg, 37. They are the only grandchildren of John F. Kennedy.

“For my whole life, I have tried to be good, to be a good student and a good sister and a good daughter, and to protect my mother and never make her upset or angry,” Tatiana Schlossberg wrote in her essay. “Now I have added a new tragedy to her life, to our family’s life, and there’s nothing I can do to stop it.”

Schlossberg was a Yale and Oxford graduate and science reporter for The New York Times, as well as the author of the 2019 book “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have.”

She spoke on TODAY in 2019 about the book and being part of the Kennedy lineage.

“I’m very proud of my family’s political legacy, but I’m also very proud to come from a family of writers because my grandfather was an amazing speechwriter, but also wrote books,” Schlossberg said. “And my grandmother was an editor, and both of my parents are writers as well, and so I feel very proud to be serving in that way, and I’m very proud to be a member of the press.”

Schlossberg also spoke about the environmental message in her book.

“I think what the book is really trying to do is talk about how this is really a collective issue,” she said. “Yes, there are things that all of us can do, but it’s not about sort of feeling individually guilty, it’s about feeling collectively responsible.”

She is survived by her husband, George Moran, and their two children.
