Jack Schlossberg Pays Emotional Tribute to His Late Sister Tatiana Schlossberg

The Kennedy family is mourning a devastating loss. Tatiana Schlossberg, the beloved sister of Jack Schlossberg and daughter of Caroline Kennedy, passed away after a courageous battle with leukemia. She was just 35 years old.

The heartbreaking news was confirmed through an official statement shared on the JFK Library Foundation’s Instagram account, released on behalf of Tatiana’s closest family members. The announcement included her husband, Dr. George Moran, their two young children, as well as her parents Caroline Kennedy and Edwin Schlossberg, her brother Jack, sister Rose, and sister-in-law Rory.

“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the family wrote, capturing the depth of their grief in a simple yet powerful message.

At this time, the family has not publicly shared details regarding funeral arrangements, asking for privacy as they navigate an unimaginable loss.

A Brave Voice Amid Illness and History

In November, Tatiana Schlossberg—an acclaimed environmental journalist and author—publicly revealed her terminal diagnosis in a deeply personal essay titled “A Battle with My Blood,” published in The New Yorker. The essay coincided with the anniversary of her grandfather President John F. Kennedy’s assassination, adding historical weight to her already emotional words.

In the piece, Tatiana described the profound support she received from her family throughout her illness, writing candidly about months spent in hospital rooms and the quiet strength of her loved ones.

“My parents and my brother and sister have been raising my children and sitting in my various hospital rooms almost every day,” she wrote.
“They held my hand unflinchingly while I suffered, trying not to show their pain to protect me from it.”

Her words reflected not only gratitude, but also heartbreak—particularly over the pain her illness brought to her mother.

“For my whole life, I tried to protect my mother,” Tatiana admitted.
“Now I have added a new tragedy to her life, and there’s nothing I can do to stop it.”

Advocacy, Politics, and a Lasting Legacy

Tatiana’s essay became one of the most emotionally charged contributions to the ongoing Kennedy family political divide. She openly criticized healthcare policies she believed endangered cancer patients and women’s medical autonomy, including positions linked to RFK Jr. and the Trump administration.

She detailed her fears about funding for leukemia research and clinical trials, as well as access to lifesaving medications used in postpartum emergencies—highlighting how political decisions directly affected her fight for survival.

Through her writing, Tatiana used her voice not only to share her pain, but to advocate for those facing similar battles. Her courage transformed private suffering into public purpose.

Jack Schlossberg’s Quiet Tribute

Just weeks before the essay’s publication, Jack Schlossberg announced his congressional campaign in New York. In a subtle but poignant show of support, he shared Tatiana’s article on social media, followed by a simple caption:

“Life is short let it rip.”

Now, those words carry even greater weight.

She was more than a Kennedy. She was a powerful voice who faced unimaginable hardship with grace and bravery.

As tributes continue to pour in, one truth remains clear: Tatiana Schlossberg will be remembered not just for who she came from—but for who she was, and the impact she chose to make.
