Jack Schlossberg is sharing a powerful piece of writing from his older sister Tatiana Schlossberg in the wake of her tragic death at 35.

Tatiana died on Dec. 30, just one month after publicly sharing her diagnosis with acute myeloid leukemia in a deeply personal and tragic essay published by The New Yorker.

Jack, Tatiana’s younger brother, remembered the environmental journalist in an Instagram post on Monday, Jan. 5, that was captioned simply with a “🌸” emoji.

The post shared 10 quotes from well-known writers and public figures, beginning with an excerpt from Tatiana’s 2022 book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have:

“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 last 10,000 years or so. … 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 same quote from Tatiana was shared by the JFK Library Foundation on Monday along with a rare photo of her with her husband, George Moran, and their two children in September.

Jack’s post included quotes from several others, including Abraham Lincoln, Robert Frost, and their grandfather, the late President John F. Kennedy. The quote from JFK reads, “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.”

The final slide in his photo showed him standing beside Tatiana seemingly during a January 2011 event at the U.S. Capitol, where the siblings are laughing with their right hands over their hearts.

Tatiana was the middle child of Caroline Kennedy and Edwin Schlossberg, and the granddaughter of JFK. Caroline and Edwin also share son Jack, 32, and daughter Rose, 37. Tatiana was the mother of two children — a 3-year-old son, Edwin, and 1-year-old daughter, Josephine — whom she shared with Moran.

Jack initially showed support for his sister after she revealed her cancer diagnosis in the essay, titled, “A Battle with My Blood.” Jack, who is currently running for Congress in New York, shared a screenshot of the emotional essay along with the link to it, on his Instagram Stories. He also separately shared a screenshot of the essay’s opening paragraph.

In her essay, Tatiana spoke about Jack’s support, writing, “My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half. They have held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it.”

Wrote Tatiana, “This has been a great gift, even though I feel their pain every day.”
