Alice Herz-Sommer, who lives in London, is the oldest living Holocaust survivor. She is also said to be the world's oldest living pianist.
Born in Prague with a remarkable musical gift, she became a concert pianist. After the Germans invaded, she was sent to Theresienstadt concentration camp, a "show camp" of artists, writers and musicians.
She gave more than a hundred concerts for the starving inmates. They had only a little black coffee and a little watery soup, but music kept them alive. "This was their food," she says.
She survived the war, and moved to London some 25 years ago. She is 109.
I wrote a blog post about her almost two years ago. Now someone has contacted me to tell me of the release of a full-length film, The Lady in Number Six, telling the story of her life.
You can see extracts from the film here.
