Rhoda Coffin, (1826–1909), was a Quaker social reformer, author, temperance crusader, and women's rights advocate who is best known for her efforts in prison reform. She held an integral role in establishing the Indiana Reformatory Institution for Women and Girls in 1869. It became the first female-controlled women's prison in the United States. She also served as president of the reformatory's board of managers. Coffin’s efforts on behalf of prison reform made her a leading figure in the national prison reform movement, and she traveled widely, wrote articles, and delivered speeches on the topic. She was also a champion of other causes that assisted women and children.
