Jean Henri Dunant (May 8, 1828 - October 30, 1910) (often called Henry Dunant or Henri Dunant) was a Swiss businessman and humanitarian who founded the Red Cross movement. He was awarded the first Nobel Peace Prize in 1901 (with Fr ric Passy).

A man deeply religious in the Calvinist tradition and committed to the principle of "Love thy neighbor," Dunant crisscrossed Europe, lecturing on the evils of slavery. While in Italy in 1859, he visited the site of the Battle of Solferino, where he was stunned by the many thousands of wounded soldiers left on the battlefield to die, without receiving even the most basic medical attention that might have saved them. Upon his return to Geneva he wrote Souvenir of Solferino, a memoir of his experiences in Italy, in which he advocated the establishment of an international network of volunteer relief agencies. The book won the attention of Switzerland's Federal Council and in 1863 that country sponsored an international conference to discuss ways to implement Dunant's ideas as he expressed them in the Nine Articles. Sixteen countries attended and by 1864 twelve ratified the document, which became the basis for the International Committee of the Red Cross and the first Geneva Convention.

In the following years, Dunant wrote prolifically on disarmament and the establishment of an international court to arbitrate conflicts between countries.
