Tatiana Schlossberg, granddaughter of the ‍35th US president, John F Kennedy, died on ‍Tuesday after revealing in a November essay that she had been diagnosed with a rare form of ‌leukaemia. 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 ‍US 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 leukaemia 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 US health secretary, for being ⁠a vaccine skeptic and cutting funding for cancer research.
