Tributes have poured in for Tatiana Schlossberg, President John F. Kennedy’s granddaughter, who died yesterday aged 35 after terminal cancer.
A family statement shared by the John F. Kennedy Library Foundation confirmed her death. In a joint message from her brother Jack Schlossberg, sister Rose, sister-in-law Rory, mother Caroline Kennedy, father Ed Schlossberg, and her husband George Moran, the family said: "Our beautiful Tatiana passed away this morning. She will always be in our hearts."
A cause of death was not formally cited, but Schlossberg—a journalist and author—revealed in a powerful and poignant New Yorker essay published in November 2025 that she had been diagnosed with a rare form of leukemia. In the piece, titled "A Battle With My Blood," Schlossberg disclosed she had acute myeloid leukemia with a rare mutation, a cancer of the blood and bone marrow, and had been given a prognosis of just one year.

In the essay, Schlossberg described learning of her diagnosis shortly after the birth of her daughter in May 2024. She wrote openly about enduring months of intensive chemotherapy, surviving a near-fatal postpartum hemorrhage, and ultimately, undergoing a stem cell transplant donated by her sister, Rose. During her treatment, her brother Jack—who is running for Congress—shaved his head in solidarity after she lost her hair.

Schlossberg’s cousin Maria Shriver paid heartfelt tribute on Instagram, writing: "I return to this space today to pay tribute to my sweet, beloved Tatiana, who left this earth today. I return to this space to pay tribute and honor her loving and supportive family, who came together and did everything they possibly could do to help her. I return to this space heartbroken because Tatiana loved life. She loved her life, and she fought like hell to try to save it."
In a lengthy post, Shriver said she was struggling to comprehend the loss and praised Schlossberg as a gifted journalist who used her voice to educate others about the environment. She described her cousin as courageous, valiant, and fiercely determined, and highlighted the life she built with her husband George and their children, Eddie and Josie. Shriver also paid tribute to Schlossberg’s mother, Caroline Kennedy, calling her a source of strength for the entire family during Tatiana’s illness.
Shriver encouraged followers to read Schlossberg’s New Yorker essay, describing it as extraordinary, and asked people of all faiths to pray for the grieving family. She remembered Schlossberg as the light, humor, and joy of the family, and said those left behind would ensure her children grow up knowing what a loving and courageous spirit their mother was. She ended by urging people to honor their own lives, calling life "such a gift."
CNN host Jake Tapper also paid tribute on X, writing, "RIP Tatiana Schlossberg. So sad," while sharing a CNN story about her death.
Actress Kimberly Williams-Paisley, known for her roles in The 10th Kingdom, According to Jim, Nashville, and Father of the Bride, also shared her condolences, writing in the comments section: "I was so sad to read that news today. Her essay was incredible. I’m so sorry for your family’s loss. Sending much love."
Writer and podcast host Cheryl Strayed added: "Maria, I’m so sorry for your loss. I will never forget Tatiana’s powerful, beautiful, heartbreaking and also life-affirming essay. My heart aches for her that she died so young. I know she’ll live on in all who loved her and were loved by her. My deepest condolences to you and your family."
American news broadcaster and author Luke Russert wrote on Instagram: "We’ll remember her and her writing for the rest of our time. What a gift she gave."
