Jack Schlossberg, the grandson of John F. Kennedy, has offered a moving tribute to his late sister, Tatiana Schlossberg, who recently died at 35 after battling cancer.
Tatiana passed away on December 30 following her struggle with Acute Myeloid Leukemia, an aggressive type of blood cancer.
On Monday, December 5, as the Kennedy family gathered for her funeral, Jack took to Instagram to remember his sister with a heartfelt tribute.
In memory of Tatiana, Jack posted ten excerpts from famous texts and poems, along with a photo of the two siblings in their younger years.
He simply added a cherry blossom flower emoji in the caption, letting the tribute’s words resonate on their own.
The first entry in the series was a piece of Tatiana’s own writing from her 2019 work, Inconspicuous Consumption.
“It’s up to us to create a country that takes seriously its obligations to the planet, to each other, and to the people who will be born into a world that looks different than ours has for the past 10,000 years or so,” Tatiana wrote.
“Essentially, what I’m describing is hard work with possibly limited success for the rest of your life. But we have to do it, and at least we will have the satisfaction of knowing we made things better.
“Come on, it will be fun (?)” the excerpt concluded.
Among the other selections were an excerpt from Moby Dick discussing whale immortality, Alfred Lord Tennyson’s poem Crossing the Bar, writings by Abraham Lincoln, and poetry by Rita S. Beer, Robert Frost, and Elizabeth Bishop.
Jack also included Buddha’s last words: “Then the Buddha addressed all the monks once more, and these were the very last words he spoke.”
“’Behold, O monks, this is my last advice to you. All component things in the world are changeable. They are not lasting. Work hard to gain your own salvation.’”
He even referenced a notable quote from their grandfather, JFK: “There are three things in life which are real: God, human folly and laughter.”
“Since the first two are beyond our comprehension, we must do what we can with the third.”
Tatiana previously disclosed her diagnosis in a heartfelt essay for The New Yorker in November 2025, revealing the difficult news and her feelings at the time.
She explained she had been asymptomatic at diagnosis and had tried various treatments to combat the disease, but ultimately faced a terminal prognosis.
In a poignant note, Tatiana addressed the ‘Kennedy curse’ in her essay, expressing her wish not to bring another tragedy to her mother Caroline’s life.
“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,” Schlossberg 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.”
Caroline Kennedy, Tatiana’s mother, is the daughter of John F. Kennedy and Jackie Kennedy, and she has endured significant personal loss, including the assassination of her father, the death of her mother from lymphoma, and the tragic plane crash that claimed her brother, JFK Jr.
