Health struggle

Schlossberg had been diagnosed with acute myeloid leukemia, a form of cancer that affects the blood and bone marrow.

She revealed her diagnosis in a heartbreaking essay published in The New Yorker in November 2025. The doctors had given her less than a year to live, Schlossberg wrote in the essay.

The disease was discovered while she was hospitalized after giving birth to her second child, a daughter. She was also mother to a son with husband George Moran.

In her essay, Schlossberg spoke about her disbelief upon receiving the diagnosis: "I did not - could not - believe...I was actually one of the healthiest people I knew."

She highlighted the unwavering support of her family during this difficult time. Her sister Rose even matched as a stem cell donor for her first transfusion.

"My brother (Jack) was a half-match, but he still asked every doctor if maybe a half-match was better, just in case," she wrote.

Schlossberg's education and writing career
Academic journey

Schlossberg had a BA in History from Yale University and a master's degree in American history from the University of Oxford.

She was an environmental writer and was working on a research project about ocean conservation before her diagnosis.

In her essay, she expressed concern about not being able to care for her daughter due to health risks after transplants. "...Don't know who...she thinks I am, and whether she will feel or remember, when I'm gone, that I'm her mother."

Personal thoughts

Schlossberg also reflected on her fears of not being remembered by her children.

"My son might have a few memories, but he'll probably start confusing them with pictures he sees or stories he hears," she wrote.

Despite the challenges, she tried to focus on living in the present with her family.

"...Since I don't know what death is like and there's no one to tell me what comes after it, I'll keep pretending. I will keep trying to remember."
