15. Clara Barton
Clara Barton, born on December 25, 1821, in Oxford, Massachusetts, was a pioneering nurse and humanitarian. During the American Civil War, she provided critical care to wounded soldiers on the front lines, earning the nickname “Angel of the Battlefield.” After the war, Barton founded the American Red Cross in 1881, serving as its first president and expanding its mission to include disaster relief and humanitarian aid (nps.gov). Her enduring legacy continues to inspire global humanitarian efforts.
