John F. Kennedy's granddaughter, Tatiana Schlossberg, has died at the age of 35. The author and environmental journalist succumbed to leukemia, a month after she announced her terminal cancer diagnosis. Her family confirmed her demise in a post on Instagram on December 30, on the John F. Kennedy Library Foundation account. "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." Tatiana Schlossberg slams cousin Robert F. Kennedy in a candid essay: Read more View this post on Instagram Instagram PostIn November, Tatiana Schlossberg penned an essay for The New Yorker announcing that she was diagnosed with acute myeloid leukemia. She described it as "terminal" at the time, adding that she learned about the same after she gave birth to her second child in May 2024. Schlossberg, who is the daughter of Caroline Kennedy and Edwin Schlossberg, disclosed that she had undergone a stem cell transplant, courtesy of her sister, and had gone into remission. Schlossberg has a brother, Jack Schlossberg, 32, and a sister, Rose Schlossberg, 37. The three are the only grandchildren of the late president. However, she relapsed, she said in her essay. “During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe,” she wrote at the time.“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 had a distinguished career, having worked for The New York Times and contributed to major publications like The Atlantic and The Washington Post. She was also the author of a book, "Inconspicuous Consumption: The Environmental Impact You Don't Know You Have," which came out in 2019. In her essay, she recalled the disbelief she experienced upon learning of her diagnosis, adding that in her latest clinical trial, her doctor told her they could "keep me alive for a year, maybe." She then went on to scrutinise her cousin, Health Secretary Robert F. Kennedy, who is notorious for his anti-vaccine stance. Tatiana Schlossberg previously called him "an embarrassment to me and the rest of the family" when he tried to run for president as an independent candidate last year. "I watched from my hospital bed as Bobby, in the face of logic and common sense, was confirmed for the position, despite never having worked in medicine, public health, or the government," she wrote.
