Barton, Clara, (1821–1912), an American philanthropist, humanitarian, and founder of the American National Red Cross. During the U.S. Civil War, she was a volunteer nurse, often on the battlefield, and at its end she organized a bureau of records to help in the search for missing men. When the Franco-Prussian War erupted, she assisted in the organization of military hospitals in Europe in association with the International Red Cross. This experience led to her advocacy of the establishment of an American Red Cross organization, of which she became the first president.
