Nobel prize was founded by a man who earned money in the first world war by creating all kinds of destructive bombs, machines.
The first world war was fought using the means supplied by Mr. Nobel. And he earned such a huge amount of money…
Both the parties were getting war material from the same source; he was the only person who was creating war materials on a vast scale. So whoever was killed, was killed by him. It doesn't matter whether he belonged to this side or to that side; whoever was killed was killed by his bombs.
So in old age, when he had all the money in the world a man can have, he established the Nobel prize. It is given as a peace award — by a man who earned the money by war!
