“The Holocaust occurred because individuals, organizations, and governments allowed prejudice, hatred, and even mass murder to occur. Young people, you can create a new way forward,” Wagner said. “You can be the change makers who create a world of unity, respect and tolerance.”

In 1976, Wagner spoke to students who were performing the same play. Since then, the school said she has come back to speak whenever possible.
