The Nobel prize is an award given in several different categories to honor people who are making a difference in the world. The prizes were established by the will of inventor Alfred Nobel, who wanted his money to be distributed to people who had worked to deserve it. The first prize was awarded on December 10, 1901 in the categories of Chemistry, Physics, Peace, Literature, and Physiology or Medicine. Later a prize was added for economic achievements. Each year the awards are given in Stockholm Sweden to people from all over the world except the Peace Prize, which is awarded in Oslo, Norway. Nobel Prize Day celebrates the anniversary of the first ever awards and the people who have received the prize throughout history.
