War began in Crimea*, present-day Ukraine, and Nightingale was sent there with 24 Catholic sisters and 14 nurses. Nightingale's efforts improved the hospital environment during the war. The Nightingale School of Nursing was established with the Nightingale Fund created during the war. Although Henri Dunant, a founding member of the International Committee of the Red Cross, highly praised her work, Nightingale was not involved in the International Committee of the Red Cross. This was because she believed that aid activities based on self-sacrifice by participants would not last long. Her famous quote, "Devotion without sacrifice is true service," expresses this well. It is said that this was due to the idea that "we rely on the spirit of service of our members, but without financial support, we are powerless." Nightingale only served wounded soldiers as a nurse for only two years during the Crimean War*, and became famous for her symbolic image of dedication and for her use of statistics to reform health care. The statistical methods she used at this time were highly praised, and she was considered a pioneer of statistics in England.
