The profile of Alfred Nobel appears on the side of the Nobel Peace Center in Oslo, Norway.

Since 1901, the awarding of the Nobel Prizes has been among the most closely watched — and, at times, the most controversial — ceremonies in the world. And the 2013 Nobel Prizes, which will be announced over several days beginning Monday (Oct. 7), will not be any different.

Alfred Nobel (1833-1896) established the Nobel Prizes in his last will and testament. Nobel stipulated that prizes should be given in five categories: Physics, Chemistry, Physiology or Medicine, Literature and Peace. In 1968, a sixth category was added: Economic Sciences.
