Alfred Nobel's will, written in 1895, left funding for a prize to be awarded 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."
The first such prize, awarded in 1901, went to Jean Henry Dunant and Frédéric Passy, two men who held and promoted peace congresses, two peace activists, two men who were not elected officials. Nor were they war makers who had exercised restraint in some instance or other. In 1902, again, the peace prize went to two peace activists. In 1903 the prize went to a member of the British Parliament, but one who had worked for peace and not for war. In 1904, the laureate was what we would now call an NGO, but one that had worked for peace and not for war. In 1905, a woman who had played a role in the creation of the prize, an author and a peace activist, someone who indeed held and promoted peace congresses, was the first female winner. And then came 1906.
