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.

According to the Cleveland Clinic, acute myeloid leukemia “typically happens when certain genes or chromosomes mutate (change). AML usually affects people age 60 and older, but it can also affect younger adults and children. [It] is an aggressive cancer that can be life-threatening.”

The illness only affects about 4 in 100,000 adults per year.

Blood Cancer United reported in November that the FDA approved a new drug called ziftomenib to treat those with advanced AML with an NPM1 gene mutation.

“In a clinical trial, 21.4% of patients treated with ziftomenib went into a full remission or remission with partial recovery of blood counts, which means there were no signs of cancer cells in the bone marrow, but not all blood counts had returned to normal.”

Fibis I am just an average American. My teen years were in the late 70s and I participated in all that that decade offered. Started working young, too young. Then I joined the Army before I graduated High School. I spent 25 years in, mostly in Infantry units. Since then I've worked in information technology positions all at small family owned companies. At this rate I'll never be a tech millionaire. When I was young I rode horses as much as I could. I do believe I should have been a cowboy. I'm getting in the saddle again by taking riding lessons and see where it goes.
