1. Japanese Diplomat in Lithuania during WW2
He was giving free travel passes to anyone who asked, especially Jews fleeing the holocaust. He was ordered by his government to stop and refused. As his embassy was being closed down, he and his wife were signing documents and handing them out to all refugees all the way to the train station; even to the point of throwing signed documents out the window as the train left.
He saved 6,000 to 10,000 lives by his actions and was later named among "the Righteous of Nations" and had his name and story entered into a museum in Israel to be forever remembered.
