World War II began in September 1939. Brigitte and her family moved to Kovno, hoping to secure visas and passports for travel to North America. In July 1941, Brigitte and her family were forced to move into the Kovno ghetto after the Germans occupied Lithuania. Brigitte's family survived the "Great Action," but her mother died of illness in the ghetto. After a roundup targeting children in March 1944, Brigitte escaped from the ghetto with the help of a former employee of her father. Soviet forces liberated Kovno in August 1944.
