Clarissa Harlowe Barton (December 25, 1821 April 12, 1912) was an American nurse who founded the American Red Cross. She was a hospital nurse in the American Civil War, a teacher, and a patent clerk. Since nursing education was not then very formalized and she did not attend nursing school, she provided self-taught nursing care. Barton is noteworthy for doing humanitarian work and civil rights advocacy at a time before women had the right to vote. She was inducted into the National Women's Hall of Fame in 1973.
