Eva Brust Cooper was born on March 18, 1934 into an assimilated Jewish family. She grew up in Budapest. Even if she herself did not notice anything anti-Semitic until much later, her grandparents, who were more concerned about Hitler than most people, decided to leave the country early. In 1939 they left on a supposed "vacation" to the United States and never returned.
Eva's father was involved in Jewish organizations and so had access to a lot of information, wasn't worried that much. But in 1942 the Hungarian government took him, like many other Jewish men, by force to labor camps and made to do heavy-duty labor.
During her 10th birthday party, March 18, 1944, she witnessed the occupation of Budapest by German soldiers out of the window.
