Margot Friedländer, a Holocaust survivor who spent more than 60 years in exile (as she saw it) in New York City before returning to Germany in 2010 and finding her voice as a champion of Holocaust remembrance — work that made her a celebrity to young Germans and landed her on the cover of German Vogue last year — died on Friday in Berlin. She was 103.

Her death, in a hospital, was announced by the Margot Friedländer Foundation, an organization promoting tolerance and democracy.

“It helps me to talk about what happened,” she told the members of a UNICEF Club in 2023. “You young people help me because you listen. I don’t bottle it up anymore. I share my story for all of you.”

Ms. Friedländer and her husband, Adolf — known in America as Eddie, for obvious reasons — arrived in New York in the summer of 1946. They settled into a small apartment in Kew Gardens, Queens. He found work as comptroller of the 92nd Street Y, the cultural center on the Upper East Side of Manhattan, and she became a travel agent.

The couple had married at the camp where they were both interned; once in America, they never spoke of their shared experience. Mr. Friedländer was adamant about never returning to the country that had murdered their families. But when he died in 1997, Ms. Friedländer began to wonder what had been left behind.

She had found a community at the Y, and, at the urging of Jo Frances Brown, who was then the program director there, she signed up for a memoir-writing class. It was weeks before she participated, however. The other students, all American-born, were writing about their families, their children, their pets. One night, unable to sleep, she began to write, and the first stories she told were her earliest childhood memories.
