Sarah Matz took the married name Anna Varshavski aka Anna Lvovna Warsaw. She was a singer and a philanthropist. She was born in Vilnius in December of 1896 when it was part of the Russian Empire. Her parents Jehuda and Fradel Matz owned a Jewish publishing house. She began studies at the Berlin Conservatory in 1920. In 1928 she set up an amateur choir in Kaunas which grew in reputation and size and eventually included around 50 members, coming to be known as the Jewel of Joel Engel Choir. They performed throughout Lithuania and on state radio. The choir disbanded in 1936. Varshavski also contributed to setting up the New Jewish Theater in Vilnius. She and her family were put in the Kaunas ghetto in 1941, and she was murdered at the Klooga concentration camp in Estonia in 1944.
