Martin Niemoeller, a German U-Boat commander in World War I who later became a Protestant pastor and pacifist. The Nazis threw him into a concentration camp. After miraculously surviving, wrote:

"When the Nazis took the communists away, I was silent; after all, I was no communist.

"When they put the social-democrats in prison, I was silent; after all, I was no social-democrat.

"When they took the trade-unionists away, I did not protest; after all, I was no trade-unionist.

"When they took me away, there was nobody left to protest."
