Sweden's Nobel Foundation begins announcing winners of the annual Nobel Prize awards on Monday in Oslo, Norway.
Prizes for medicine, physics, chemistry and literature will be announced before the prestigious Peace Prize is revealed Friday.
A separate prize for economics will be announced October 10. It was instituted in 1968 by the Bank of Sweden in memory of the founder of the Nobel Prize, Swedish philanthropist Alfred Nobel.
Winners receive their awards, including a check worth $1.3 million, at a banquet on December 10. That is the anniversary of Mr. Nobel's death in 1896.
According to his will, a five-member committee elected by the Norwegian parliament chooses the Peace Prize laureate, while Swedish scientific and literary groups choose the other winners.
The first Nobel Prizes were given in 1901.Some information for this report provided by AP and AFP.
