The worldwide Organization of the Red Cross stems from the idea of Henri Dunant, a Swiss banker. In 1838, at the age of ten, Dunant was taken by his father to visit a prison, where he saw prisoners chained together exercising in the yard and breaking stones along the road. This experience left a deep impression on him, and made him determined to do something for convicts and slaves and for all who were oppressed and deprived of their liberty.
    On June 4th, 1859, while on his way from Geneva to France, Dunant witnessed the battle between the French and Austrian armies. It was one of the fiercest battles of the 19th century. Shocked by the lack of medical supplies and attention given to the wounded, Dunant decided that volunteer service had to be organized. He gathered together a number of women who attended the hundreds of wounded soldiers of all nationalities and helped the surgeons as possible as they could.
