The Nobel Peace Prize 1912
The Nobel Peace Prize 1912 was awarded to Elihu Root.
Elihu Root received his Nobel Prize one year later, in 1913. During the selection process in 1912, the Norwegian Nobel Committee decided that none of the year's nominations met the criteria as outlined in the will of Alfred Nobel. According to the Nobel Foundation's statutes, the Nobel Prize can in such a case be reserved until the following year, and this statute was then applied. Elihu Root therefore received his Nobel Prize for 1912 one year later, in 1913.
