The entire crowd inside the Holocaust Documentation & Education Center on Sunday joined in singing the national anthem of Israel.
It was the opening of the exhibit: Operation Finale: The Capture and Trial of Adolf Eichmann.
The Nazi official orchestrated much of the Holocaust. He was hanged in Israel in 1962.
More than 500 people came to see the exhibit, which features original documents from when Eichmann was captured in Argentina, and artifacts from his trial.
