Meet Norman Borlaug.
When this man won the Nobel Peace Prize, he was directly and personally credited with saving the lives of more than a billion people.
He got his doctorate in plant pathology, then immediately went to some of the poorest places in the world. He lived for decades in a small shack with a dirt floor while he worked to create new breeds of crops that could be grown in some of the most inhospitable places on earth.
He singlehandedly started the Green Revolution, preventing what would otherwise have been the largest mass starvation in human history. Billions of people owe him their lives, and yet most people have never heard of him.
I don't much cotton to the idea of “heroes” - so don't often use the word hero, but this man is a genuine hero.
