Tatiana Schlossberg, aged 35, tragically passed away on December 30, shortly after publicly announcing her diagnosis of acute myeloid leukaemia. Her brother, Jack Schlossberg, the grandson of former US President John F. Kennedy, has since recounted her final words to him, revealing the deeply supportive nature of their relationship.

In a recent interview with CBS News Sunday Morning, Jack discussed how his sibling encouraged him in his political aspirations to represent New York’s 12th Congressional District in the US House of Representatives. When asked about Tatiana’s thoughts regarding his campaign, Jack reflected on her last message to him, stating, “I can tell you now that she’s still rooting for us. The last thing that she said to me was, ‘You better win.’ No one knew me better, and I knew no one better than her.”
Tatiana’s passing was announced by the JFK Library Foundation via an emotional Instagram tribute, expressing how much she would be missed. “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the post read, signed by family members. The Schlossberg siblings share a close-knit relationship, with Jack previously sharing the challenges of growing up alongside his two sisters.
Reflecting on his upbringing, Jack admitted, “It’s brutal. Absolutely brutal. They don’t let you get away with anything. My style is never good enough. I’ve never gotten an answer right in my entire life. But in all honesty, they taught me everything I know about how to be a strong person.” This insight highlights the profound impact Tatiana and his other sister, Rose, had on shaping his character.
Tatiana was a devoted mother to two young children—son Edwin, born in 2022, and daughter Josephine, born in 2024—with her husband, George Moran. Jack described himself as “the best uncle,” emphasising the importance of family ties within their lives. “We’re a really close family,” he noted. “When you talk about the Kennedy family, it’s a lot of people I don’t know. When you talk about what family is, it’s me, my sisters, my parents. We’re a unit and we’re really close.”
Following Tatiana’s death, Jack continued his congressional campaign, imbued with her spirit and supportive messages. Just weeks later, he participated in a rally supporting the New York State Nurses Association, echoing a recurring theme in their discussions. “Nurses should rule the world, if you ask me,” he asserted during the rally, aligning his campaign message with Tatiana’s advocacy for the medical profession.
Previously, in November, Tatiana had shared her diagnosis through a personal essay published in The New Yorker, in which she shared her sentiments about healthcare and her appreciation for nurses. “Nurses should take over,” she had stated, advocating for the importance of their role within the healthcare system. This bold assertion reflected her dedication to promoting awareness and support for the nursing community, particularly during her own health struggles.
Days after her passing, on January 5, Jack shared a poignant tribute on social media, posting a heartfelt piece written by Tatiana alongside ten quotes from notable writers and public figures. The final image captured a moment of unity between the siblings, displaying them with their hands over their hearts at the U.S. Capitol—an image that speaks volumes about their bond and shared values.
In the face of grief, Jack Schlossberg continues to honour his sister’s legacy through his congressional efforts, bringing attention to vital social issues and maintaining the familial connection that defined their relationship. As both a brother and an advocate, he embarks on a journey that not only commemorates Tatiana’s life but also continues her passion for social justice and healthcare reform.
