The winner of the 2015 Nobel Peace Prize will be announced Friday morning. This year, 273 names are known to be on the list of nominees, but those names will be kept secret for 50 years, as is Nobel tradition. German Chancellor Angela Merkel and U.S. Secretary of State John Kerry are among those speculated to win the highly acclaimed award.

Swedish chemist and business tycoon Alfred Nobel is the man behind the annual international prizes for peace, chemistry, literature, physics and medicine. Nobel invented dynamite and amassed great wealth from patenting the lethal explosive in 1867. Before he died, on Dec. 10, 1896, Nobel gave the largest share of his fortune in his last will to a series of prizes, dubbed the Nobel Prizes.

Here are 10 facts about the Nobel Peace Prize:

1. As described in Nobel’s last will and testament, the Nobel Peace Prize was dedicated to “the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies, and for the holding and promotion of peace congresses.” Nobel also declared that the peace prize should be awarded by a Norwegian committee. All other Nobel Prizes are awarded in Stockholm.

2. Ninety-five Nobel Peace Prizes have been awarded since 1901. It was not awarded on 19 occasions, and fewer prizes were awarded during the years of World War I and II. "If none of the works under consideration is found to be of the importance indicated in the first paragraph, the prize money shall be reserved until the following year. If, even then, the prize cannot be awarded, the amount shall be added to the Foundation's restricted funds,” according to the statues of the Nobel Foundation.
