Woman's Work in the Civil War, 1867, by Linus Pierpont Brockett M.D. and Mary C. Vaughn.
“Clarissa ‘Clara’ Harlowe Barton (December 25, 1821 – April 12, 1912) was a pioneering nurse who founded the American Red Cross. She was a hospital nurse in the American Civil War, a teacher, and patent clerk. Nursing education was not very formalized at that time and Clara did not attend nursing school, so she provided self-taught nursing care. Barton is noteworthy for doing humanitarian work at a time when relatively few women worked outside the home.” – Wikipedia
