Nobel preferred not to be remembered as the inventor of the dynamite, so in 1895, just two weeks before his death, he created a fund to be used for awarding prizes to people who had made world while contribution to mankind. Originally there were five awards: literature, physics, chemistry, medicine and peace. Economics was added in 1968, just sixty- seven years after the first awards ceremony. Nobel’s original legacy of nine million dollars was invested and the interest in this sum is used for the awards which vary from $ 30,000 to $ 125,000.
