Oh man how much time do I have? I have a lot. There are so many unknown heroes in history that never got the respect they deserved. If I had to choose one man as an outstanding human being, it would this man; Chiune Sugihara.
Sugihara was serving a diplomat and informant on Nazi movement on behalf of Japan in Lithuania during World War II. Part of his job was issuing visas to people traveling to Japan, granting them safe passage until they reach the island nation.
After Russia occupied Lithuania, putting both fleeing Polish Jews and Lithuanian Jews in danger, Sugihara realized he had to do something. He contacted his higher ups in Japan, asking for permission three times to issue visas to save these people. They told him no, he was not to issue any visas all three times.
With little options and encouragement from his wife to do the right thing, Sugihara disobeyed his orders and began to issue visas to Jews to grant them access to Japan. He not only knew his job was finished, but he had just broken serious Japanese social and business rules. You do not disobey orders from a senior, that's completely out of the question. But Sugihara did, and he spent the next month signing as many visas as he could, spending up to 20 hours a day doing so. It was a race against time, as the Russian occupancy was set to close the consulate.
When the consulate finally closed, he boarded his train with his wife, desperate Jews banging on the train begging for visas. Sugihara began throwing blank visas with just his signature on them out the windows as the train pulled away, saving more lives in this final act.
When he returned to Japan, Sugihara resigned (his wife claimed he was forced to due to the visas) and worked menial jobs. In Israel, Sugihara is a celebrated hero, but back in his native Japan most people didn't even know what he had done. Even Sugihara didn't know how many people he had saved.
It's estimated that Chiune Sugihara's incredible act of defiance saved 6,000 Jews.
