Zuzana Ruzickova (14 January 1927 – 27 September 2017) was a Czech harpsichordist. An interpreter of classical and baroque music, Ruzickova was the first harpsichordist to record Johann Sebastian Bach's complete works for keyboard, in recordings made in the 1960s and 1970s for Erato Records. As a teenager, Ruzickova was imprisoned in the Nazi concentration camps of Terezin and Auschwitz, and then transported to the Bergen-Belsen death camp. She was liberated in April 1945 and returned to Plzeň later that year. Ruzickova was the wife of Czech composer Viktor Kalabis. The couple both refused to join the Czechoslovak Communist Party which held power from 1948-89, and faced political persecution as a result. Ruzickova performed across the world for 50 years, recorded over 100 records, and taught such prominent musicians as Christopher Hogwood, Ketil Haugsand, Jaroslav Tůma, and Mahan Esfahani.
