(JTA) — A documentary about the world’s oldest Holocaust survivor won an Oscar one week after she died.

Alice Herz-Sommer, who died in London on Feb. 23 at the age of 110, was the subject of “The Lady in Number 6: Music Saved My Life,” which won the Academy Award for documentary short on Sunday night.

The Prague-born Herz-Sommer, a concert pianist, was a prisoner in Theresienstadt.

In accepting the Oscar, the film’s director, Malcolm Clarke, said he was struck by Herz-Sommer’s “extraordinary capacity for joy” and “amazing capacity for forgiveness.”
