She lived for 40 years in Israel, before emigrating to London in 1986, where she resided until her death, and at the age of 110 was the world's oldest known Holocaust survivor until Yisrael Kristal was recognized as such.Herz's older sister Irma taught her how to play the piano, which she studied diligently, and the Austrian-Jewish pianist Artur Schnabel, a friend of the family, encouraged her to pursue a career as a classical musician, a choice she decided to make.[7] She began giving concerts and making a name for herself across Europe until the Nazis took over Prague, as they did not allow Jews to perform in public, join music competitions or teach non-Jewish pupils.After the invasion of Czechoslovakia, most of Herz-Sommer's family and friends emigrated to Israel via Romania, including Max Brod and brother-in-law Felix Weltsch, but Herz-Sommer stayed in Prague to care for her ill mother, Sofie, aged 72; both women were arrested and Sofie Herz was murdered in a concentration camp.[5] In July 1943 Herz was sent to Theresienstadt, where she played in more than 100 concerts along with other musicians, performing pieces by Beethoven, Bach, Brahms, Schumann, and Chopin among other Czech composers[8] for prisoners and guards.[4][7] After the Soviet liberation of Theresienstadt in 1945, she and Raphael returned to Prague, and in March 1949 emigrated to Israel, to be reunited with some of her surviving family, including her twin sister, Mariana."[9] Her son Raphael, an accomplished cellist and conductor, died in 2001, aged 64, of an aneurysm in Israel at the end of a concert tour.[14][15][16] Herz-Sommer was the subject of A Garden of Eden in Hell, first published in German in 2005 (reprinted in English as Alice's Piano).
