Tatiana Schlossberg, a climate and environmental journalist and the granddaughter of former President John F. Kennedy, died Tuesday at age 35, her family announced.
News of her death was shared in a social media post from the John F. Kennedy Presidential Library and Museum.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the family wrote.
Schlossberg was the second child of Caroline Kennedy, a former U.S. diplomat and JFK’s daughter, and Edwin Schlossberg, a designer and artist.
In a New Yorker essay published in November, Schlossberg revealed she had been diagnosed with acute myeloid leukemia with a rare mutation—a cancer that affects the blood and bone marrow.
In that same essay, she also condemned her cousin, U.S. health secretary Robert F. Kennedy Jr., for promoting vaccine skepticism and for supporting cuts to funding for cancer research.
