Henry Dunant
'Henry Dunant won the very first Nobel Peace Prize in 1901.
Passing through Solferino, Italy, during the Second Italian War of Independence, Dunant was appalled at the suffering that he saw. In 1862, he published a book, A Memory of Solferino, which described the efforts that were being made to care for the wounded at the scene. He also proposed a plan.
Dunant suggested the nations of the world should form their own relief societies to care for the wounded and train volunteers on the best ways to treat them. He also wanted the governments of the world to guarantee that wounded soldiers would be treated and that those treating them would be guaranteed safe passage.
Dunant traveled all over Europe promoting his plan, and on August 22, 1864, 12 nations signed the first Geneva Convention, agreeing to “guarantee neutrality to sanitary personnel, to expedite supplies for their use, and to adopt a special identifying emblem—in virtually all instances a red cross on a field of white.”
Henry Dunant had helped to bring about the first Geneva Convention, which has saved the lives of thousands of soldiers around the world. He also founded the Red Cross.’
