Marion Wiesel, who served as an advisor and translator to her husband, the late Nobel laureate Elie Wiesel, has died at 94, the New York Times reports.

Marion Wiesel was born in Vienna in 1931. When Nazi Germany annexed Austria in 1938, she and her family fled, first to Belgium and then to France. After the Nazi occupation of France, the family was imprisoned at the Gurs internment camp; two years later, they escaped, eventually moving to the U.S. in 1949.

She met Elie Wiesel, a fellow Holocaust survivor, in the 1960s, and they married in 1969. Marion Wiesel translated 14 of her husband’s books from French into English, including The Oath, A Jew Today, and The Trial of God. Her most famous translation was the 2006 edition of Elie Wiesel’s memoir of Auschwitz, Night, which had previously been translated in 1960 by Stella Rodway. The book was selected by Oprah Winfrey for her influential book club and became a No. 1 New York Times bestseller.

Marion Wiesel also served as a media advisor for her husband, solidifying his career as a public speaker who frequently appeared on television to speak about a wide range of subjects. She worked extensively with the Elie Wiesel Foundation for Humanity, which she and her husband founded in 1986.

Marion Wiesel was remembered on social media. On the platform X, Danny Danon, Israel’s permanent representative to the United Nations, wrote, “I am deeply saddened by the passing of Marion Wiesel. Her presence at the UN’s International Holocaust Remembrance Ceremony each year was a testament to her unwavering commitment to memory and truth. My heartfelt condolences to her family. May her memory be a blessing.”

And Jonathan Greenblatt, CEO of the Anti-Defamation League, posted, “Such sad news. Marion Wiesel…was a lioness in every sense of the word. She was a hero to the Jewish community, an inspiration to the world, and perhaps most of all, a beloved mother and a treasured grandmother. May her memory always be a blessing.”
