The observance also came with a message about the rising tide of anti-Semitism and other forms of hatred and bigotry.

It’s been nine years since the museum opened and 75 years since the Warsaw Ghetto Uprising.

Mayor Rahm Emanuel joined holocaust survivor Fritzie Fritzshall and other museum leaders to commemorate the two anniversaries.

The Illinois Holocaust Museum has a new temporary exhibit about the Warsaw Ghetto Uprising and the Jewish fighters who died battling Nazi forces.

At a press conference, the museum’s CEO pointed to a recent survey that exposed troubling gaps in knowledge about the Holocaust, especially among young people. At the same time, she says hate offenses are rising.

The message on Thursday is that everyone must take a stand against injustice and history should not be forgotten.
