Description When Dr. Martin Luther King Jr. gave his "I Have a Dream" speech at the March on Washington, he did not stand alone. He was joined by Rabbi Joachim Prinz, a refugee from Nazi Germany, who also addressed the crowd. Though Rabbi Prinz and Dr. King came from very different backgrounds, they were united by a shared belief in justice. And they knew that remaining silent in the face of injustice was wrong. Together, they spoke up and fought for a better future.
