The Holocaust Memorial Center Zekelman Family Campus in Farmington Hills, Mich., will hold a virtual event and film screening of the documentary “Hidden” on July 30, along with an interview with Holocaust survivor Miriam Ferber.

The event is timed to Tisha B’Av, the Ninth of the Jewish month of Av—the day when the First Temple in Jerusalem was destroyed in 586 BCE and the rebuilt temple destroyed by the Romans in 70 C.E. It has since become a period of communal mourning for numerous tragedies in Jewish history.

Tisha B’Av begins at sundown on July 29 and ends after sundown the next day, marked by a 25-hour fast and rituals associated with Jewish mourning.

Developed and produced by Project Witness, a nonprofit Holocaust resource center, “Hidden” details the sage of Jewish children concealed during the years of World War II and the Holocaust, when tens of thousands of them took on new identities to attempt to survive Nazi Germany.

Holocaust center director of education Ruth Bergman will conduct a 7 p.m. online interview with Ferber, who was born in Sosnowiec, Poland; “relocated” to the Srodula ghetto in December 1942; and then smuggled out by a righteous gentile couple who adopted her. Her immediate family perished in the Holocaust.

The film can be viewed from 10 a.m. to 10 p.m. The 7 p.m. interview will be live-streamed, both at: www.holocaustcenter.org.
