Jack Schlossberg mourns sister Tatiana as Kennedy family confirms her death at 35
NEW YORK CITY, NEW YORK: Jack Schlossberg joined his family in paying tribute to his late sister, Tatiana Schlossberg, after the environmental journalist and author died following a battle with leukemia. She was 35.
The news was confirmed earlier Tuesday through a statement shared on the JFK Library Foundation’s official Instagram account, announcing that Tatiana died earlier that morning surrounded by family. “Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the family wrote.
Kennedy family confirms death and shares brief statement
The family did not disclose additional details surrounding Tatiana’s death, nor did they announce funeral arrangements. Representatives for the Kennedy family have not commented beyond the public statement.
Tatiana was the daughter of Caroline Kennedy, the former US ambassador to Australia, and daughter of President John F Kennedy. She was also the niece of the late Sen. Robert F Kennedy, and a member of one of America’s most storied political families.
Despite her lineage, Tatiana largely carved out a private life focused on journalism, environmental advocacy, and family.
Tatiana Schlossberg revealed terminal diagnosis in New Yorker essay
In November, Tatiana publicly revealed her terminal diagnosis in a deeply personal essay titled 'A Battle with My Blood,' published in The New Yorker on the anniversary of her grandfather’s death.
In the piece, she reflected on her illness, her family’s constant presence, and the emotional toll of watching loved ones suffer alongside her.
“My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half,” she wrote. “They have held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it.”
She also expressed heartbreak over the burden she felt her illness placed on her family, particularly her mother.
“For my whole life, I have tried to be good… and to protect my mother and never make her upset or angry,” she wrote. “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.”
Essay addressed healthcare, cancer research, and politics
Tatiana’s essay went beyond personal reflection, touching on broader concerns about healthcare policy, cancer research funding, and women’s medical access.
She specifically referenced worries about leukemia research funding, and clinical trials, as well as her experience receiving misoprostol following a postpartum hemorrhage, a medication that has become politically contested due to its use in abortion care.
“I worried about the trials that were my only shot at remission,” she wrote, connecting her illness to larger policy debates affecting patients nationwide.
The essay marked one of the most direct and public political critiques from within the Kennedy family in recent years.
Jack Schlossberg shared essay weeks before announcing run for Congress
The essay was published just weeks before Jack Schlossberg announced his campaign to run for Congress in New York. At the time, he shared a link to Tatiana’s piece on Instagram.
He followed it with a post captioned: “Life is short — let it rip.”
The message has since taken on added weight following his sister’s death.
Tatiana Schlossberg is survived by her husband, George Moran, and their two children. She will be remembered for her work as an environmental journalist, her fierce intellect, and the clarity with which she chronicled both her illness and her love for life.
