Alfred Nobel was a Swedish chemist who lived from 1833 to 1896.Alfred and his brother made explosives,but in 1864 there was an accident in the laboratory and Alfred's brother was killed.Alfred then decided to spend his life trying to make explosives safer to use.
One of the strongest explosives at that time was nitroglycerin.This explosive,which looks like oily water,is very dangerous to use or even to carry.Nobel wanted to study nitroglycerin so he could find a way to make it safer,but the Swedish government would not let him make any more explosives in his laboratory.It was too dangerous.Nobel had the idea of taking nitroglycerin out on a boat in the middle of a lake and working with it there.
When Nobel wanted to take the nitroglycerin he was working with from one place to another,he put it into small boxes.Then he put the small boxes into a larger box made of clay.One day,when he opened the large clay box,he found that nitroglycerin was coming out of one of the small boxes.To his surprise,the large clay box was still dry.
This gave him the idea of mixing clay with nitroglycerin.The clay would take the oil out of nitroglycerin and make it safer.He called this new explosive 'dynamite'.
Dynamite was very useful.Alfred Nobel made and sold so much of it that he became a very rich man.In his will he gave a lot of his money to the Swedish Academy of Arts and Sciences.He wanted the money to be used to give prizes to people who did excellent work.The Academy called them 'Nobel Prizes'.The winners get a lot of money.
Nobel wanted one of the prizes to be given to people who work for peace because he hated war and he did not want people to remember him as 'the dynamite man'.Some very famous people have won the Nobel Peace Prize,including Nelson Mandela of South Africa.The United Nations Peacekeeping Forces won the prize in 1988.Nobel Prizes are given out on 10 December - the date that Nobel died.
