Alice Herz-Sommer, the world's oldest known Holocaust survivor and the subject of an Oscar-nominated documentary, has died in London aged 110, her family announced Sunday.
Herz-Sommer, originally from Prague in what is now the Czech Republic, spent two years of World War II in Czechoslovakia's Terezin concentration camp, where she entertained inmates by playing the piano.
Her grandson, Ariel Sommer, said: "Alice Sommer passed away peacefully this morning with her family by her bedside. Much has been written about her, but to those of us who knew her best, she was our dear 'Gigi'.
"She loved us, laughed with us, and cherished music with us. She was an inspiration and our world will be significantly poorer without her by our side. We mourn her loss and ask for privacy in this very difficult moment."
According to an update on the Facebook page for her Oscar-nominated film "The Lady In Number 6: Music Saved My Life", she died on Sunday after a short illness.
"She was still living in her apartment, when she fell ill on Thursday, she spent two nights in hospital and passed this morning," it said.
The 38-minute film, in which she shares her life story and describes the importance of music and laughter for a happy life, is up for best short documentary at Sunday's Academy Awards.
Producer Nicholas Reed said of the film: "Kids all over the world grow up on superheroes, what we, their parents, must remind them, is documentaries tell stories about 'real superheroes.'
