Tatiana Schlossberg, ‌granddaughter ​of the 35th ‌U.S. president, John F. Kennedy, ​died on Tuesday after revealing in a ‍November essay that she ​had been diagnosed with ​a ⁠rare form of leukemia. She was 35.

Her passing was announced by her family 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 a climate change and environmental journalist and the second child of JFK’s daughter, former U.S. diplomat Caroline ​Kennedy, and the designer-artist Edwin Schlossberg.

In a New Yorker essay published in November, Schlossberg said she had been diagnosed with acute myeloid leukemia with a rare mutation, a cancer of the blood and bone marrow.

At the time, she also criticized her cousin Robert ​F. Kennedy Jr., the U.S. health secretary, for being a vaccine skeptic and cutting funding for cancer research.
