In November, Tatiana Schlossberg wrote a New Yorker essay wherein she detailed her journey with a rare and deadly form of leukemia. When she was first diagnosed, she and her doctors believed that there could be some path forward, some treatment to be explored. But by the time she wrote her New Yorker piece, she had made some kind of peace with the fact that her leukemia was now terminal. Tatiana passed away this week at the age of 35. She is survived by her mother, Caroline Kennedy, and her father Edwin Schlossberg, as well as her two siblings Jack and Rose. Tatiana was also married to the love of her life, Dr. George Moran, and she left behind two young children, Edwin and Josephine. I cannot even imagine what Tatiana’s parents, husband, siblings and children are going through right now.
Tatiana Schlossberg, the middle child of Caroline Kennedy and Edwin Schlossberg, died on Tuesday, Dec. 30, at age 35.
The news was shared by the social media accounts for the JFK Library Foundation, on behalf of Tatiana’s extended family.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” read the post, which was signed by “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”
Schlossberg announced that she had been diagnosed with acute myeloid leukemia in an essay published by The New Yorker in November 2025.
She shared that doctors found the disease while she was in the hospital after giving birth to her second baby, a daughter. Schlossberg and husband George Moran, who tied the knot in 2017, also share a son.
“I did not — could not — believe that they were talking about me,” she wrote of her diagnosis, which would require chemotherapy and a bone-marrow transplant. “I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew.”
Thinking again of Caroline, having to bury her father, mother, brother and now her child. What that poor woman has endured is unimaginable. And Tatiana’s widower and children… it’s absolutely devastating. Our thoughts and prayers are with the Kennedys, Schlossbergs and Morans.

May she RIP!!!
Heartbreaking. May she Rest in Peace
RIP Tatiana.
It’s just devastating. Her parents, her siblings, her husband and babies…she was too young to die. May she rest in peace and may her young family find comfort one day.
Incredibly sad. RIP.
This is so sad. I wasn’t expecting her to pass away so soon. All the best to her family.
My heart aches for her family. I had hope that she could stay on through 2026. How she must have rallied the strength to pen her excellent essay before leaving the world. She had so much to give
I have so much admiration for her. I can’t stop thinking about her writing that beautiful essay in the little time she had left on Earth. It’s utterly heartbreaking, and all of my thoughts are with her family and friends.
This is just so heartbreaking. May she rest in peace and may her family find comfort in each other and their memories of her.
Her suffering sounds terrible, I hope she has found peace.
🙏🏾🥀💔
This is so sad and heartbreaking for all of Tatiana’s family and friends, but especially her kids.
Too bad her uncle Brainworm doesn’t believe in science, and has halted or defunded so many cancer-related drug and treatment trials.
This is so heartbreaking, I’m crying.
Truly tragic. May her memory be a blessing.
The part of her article that broke my heart the most was her worrying that her son won’t remember her and that she never got to bond with her baby daughter because she was either away getting treatment or she was just too sick.
That part broke me, too.
I have three kids. From the time they were born not only I have I been constantly concerned about keeping them alive but I also became acutely aware of my own mortality. I must stay alive to raise them. I must be remembered as a good, loving mother. I must make happy childhood memories for them. I must create a network of stable and supportive people for them, people that they can rely on if I’m not alive.
I needed therapy to help me manage those feelings. My kids are now in high school and middle school and I have calmed down a lot. Their father, my partner, has also done a tremendous job in raising them.
Tatiana’s family will undoubtedly do a fantastic job in keeping her memory alive for her precious little children. My heart truly goes out to them.
💔
Also, I teared up when I read that she was so concerned for the pain her death was going to cause, and that her whole life she tried to be a good student, sibling, and to never cause any upset to her mother. But truly heart-breaking for the children to lose their mother so soon. I remember when Jacquie Kennedy wrote that she did everything she could to live a healthy life when she was diagnosed with cancer. There is so much truth to the adage that so often the good die young.
I remember Jackie’s passing & in the weeks/months that followed, people did point out that her one unhealthy habit was smoking, which was carefully evaded in photos. Having said that, in early 2000s, I attended the funeral of a young woman who died of lung cancer even though she *never smoked*, leaving behind 2 preschool-age children, also a boy & girl. And now I’m reading/watching reports that there are more lung cancer diagnosis among never smokers. More young people (20s & 30s) getting colorectal cancers…
This is precisely why the halted research programs are essential/vital/critical. Uncle Brainworm indeed — he does not deserve to carry his father’s initials & it has become a lazy practice in the media, where they cannot be bothered to type out Robert/Bobby Kennedy (Jr)
It’s terrible. That’s what so many people with cancer say. And this young mother expresses what so many others feel. I’m healthy, everything is working perfectly, what’s going on? It’s simply this uncontrolled cell division that ultimately destroys the function of healthy organs. I wish everyone who is struggling with this the strength to accept it and the courage to go through with the treatment – but also the strength to let go when necessary and place themselves in the hands of the higher power that welcomes us all. I wish this young family the opportunity to feel gratitude, together with other people, that this dear person was able to spend time on our earth, and I bow deeply to the pain they are suffering.
As someone in the middle of my own cancer treatment, stories like this just hit way too hard. I am so sorry for her family, particularly those babies who will feel her absence their entire lives. And Caroline has faced too much tragedy for one lifetime. I don’t know how she does it.
Sending you love and light during your treatment.
Wishing you the best, M.
Wishing you only the very best of outcomes.
This is heartbreaking news. My prayers are with all of her loved ones. I can’t imagine the pain her family are going through. May their memories and love they gave and received from her be what comforts them in this world without her. And may she Rest in Peace 🙏.
This hurts my heart, 35 years old…
I read her book several years ago about practical actions against climate change and then read her heartbreaking essay about leukemia in November. She was special.
I had to look up a name in the family note. Tatiana’s sister, Rose, is married to Rory.
Peace to her wonderful Spirit.
Deep condolences to her family and friends.
It is telling that neither the Guardian nor the Daily Fail have mentioned her passing or even the dreadful post Trump put out about them all.
Yeah, Trump — the monster that he is — chose the day JFK’s granddaughter died as the day to repost his moronic followers’ posts calling for the Kennedy Center to be named after Trump only.
Tatiana Schlossberg’s piece gutted me more than Tolstoy’s “The Death of Ivan Ilych” which I’ve read about ten times. I saw today that “biographies” of Schlossberg have mushroomed on amazon.com.
I would beg people not to purchase one of those: get to know her through her witty and well-informed book, “Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have”.
This strongly researched and serious, yet delightfully witty, book should be required reading for anyone who cares about the essence of the Kennedy family at their best. Her recent article, “A Battle with My Blood,” made me think blood had two references: her literal blood and her “blood” relation with RFK, jr.
Unbearably heartbreaking.
