Thread: 10 Best (most moral) individuals in history?

There are lists for the 10 most evil men in history. There are also lists for the ten most evil women in history. Examples of these are: http://listverse.com/history/top-10-most-evil-men/ , http://listverse.com/crime/top-10-most-evil-women
What about the 10 most moral/best individuals in history? What about the 10 people who's actions have helped relieve the suffering of humanity the most?

I wouldn't know a single one.
