Clara Barton was born in 1821 in Massachusetts and showed an early interest in helping others, such as when her brother was injured. She worked as a teacher and clerk before gaining permission in 1862 to travel to Civil War battlefields, where she brought medical supplies. Barton helped countless soldiers and identified thousands of missing Union troops. She went on to found the American Red Cross in 1881, inspired by her work with the International Red Cross during the Franco-Prussian War. Barton helped prepare for and aid people in emergencies until her death in 1912 at age 90.
