Panelists explored the inspiring story told in the documentary The Seven Boxes, and how preserving Holocaust evidence and researching our own family trees can deepen understanding of history.

After fleeing Nazism, many Jews concealed their identities to survive and protect their loved ones. Following the war, these Holocaust survivors and their descendants struggled to find those left behind. Learn how personal artifacts help families piece together their past.

The Seven Boxes features Dory Sontheimer, whose parents escaped Nazi Germany and raised her as a Catholic. After their deaths, she followed their trail of letters, photographs, and documents and discovered relatives in six countries.

Michael Gruenbaum

Michael Gruenbaum was born in 1930 in Prague, Czechoslovakia, into a family active in the Jewish community. The Nazis dismantled Czechoslovakia in 1938–39 and occupied Prague in 1939. Michael’s father was arrested by the Gestapo in 1941 and killed. Michael, his mother, Margaret, and sister, Marietta, were sent in 1942 to the hybrid camp-ghetto Theresienstadt, where they survived the war because his mother, forced to labor in the toy-making shop, repeatedly got them exempted from deportations. They lost all their relatives and immigrated in 1950 to the United States via Cuba. Michael graduated from MIT, served in the US Army, and built a government and private-sector career in city planning and public works. He and his late wife, Thelma, have three sons.
