Pastor Martin Niemöller
was a German theologian and Lutheran pastor. He is best known for his opposition to the Nazi regime during the late 1930s and for his widely quoted 1946 poem "First they came ..."
“First they came for the Communists, and I did not speak out—Because I was not a communist. Then they came for the trade unionists, and I did not speak out—Because I was not a trade unionist. Then they came for the Jews, and I did not speak out—Because I was not a Jew. Then they came for me—and there was no one left to speak for me.”
