By the time World War II ended and Zuzana Růžičková had recovered her health, her hands were in such terrible shape that her teacher cried when she saw them. She went on to have a successful concert career, including frequent visits to the West, and became the first person ever to record Bach’s complete works for harpsichord. Now she’s 90 and no longer performing, but still active – and if you’re playing for her in a lesson and she gets bored, she’ll pick up a novel.
