Eva Fahidi, a Holocaust survivor who late in life began speaking out and writing about her experiences, as well as expressing them in dance, died on Sept. 11 in Budapest. She was 97.

After the war ended in 1945, Ms. Fahidi kept her experiences at Birkenau largely to herself for more than a half-century. Then, in 2003, on the anniversary of the day when she last saw her family members, she visited the Birkenau site and was disappointed to find is more like a tourist attraction than like anything she remembered.

She committed herself to telling her story. Over the next 20 years, she spoke to schoolchildren and worked with young volunteers who collected Holocaust remembrances from survivors. Her vehicle for doing so: dance. She engaged in a 100-minute performance that mixed dance and dialogue as it brought out her Holocaust memories.
