by making nitroglycerine，which was an effective but very dangerous explosive.One day Alfred arrived home to find that his 20yearold brother Emil had been killed in a nitroglycerine explosion.Alfred became determined to invent a safer explosive.The result was dynamite (黄色炸药)，which became an immediate success all over the world.
Alfred Nobel always wanted dynamite to be used for peaceful tasks.And when it was used to explode a path for the Panama Canal in 1914，he couldn't have been happier.Unfortunately，in the same year，the First World War started，and，when it ended four years later，dynamite had been used to take away the lives of thousands of young men.To see his invention being used in this way made him very sad.
Sometime later Alfred's older brother Ludwig died.One newspaper accidentally printed Alfred's obituary (讣告) instead of his brother's.The obituary described Alfred as a man who had become rich by inventing a weapon (武器) of mass destruction.When Alfred read this review of his life，he was very unhappy and decided to do something about it.He decided that he would use the great fortune that he had made to reward people who had been working to improve the good in society.The five awards he created were for physics，chemistry，medicine，literature and，most significantly，peace.
In 1997 the Nobel Peace Prize went to an American called Jody Williams for her efforts to get landmines banned (禁止)．Ironically，of course，the Nobel family fortune had been built on mines.Perhaps now，Alfred Nobel will rest more easily in his grave.
