Born in 1832, Mary Walker was raised in a progressive New York household. Her parents raised all six of their children to be independent with a strong sense of justice. Mary was raised to question and challenge restriction in a household where the farm work was shared equally by both parents regardless of gender. As a child, Mary worked on the family farm, rarely wearing women’s clothing as she found it to be too restrictive for farm work.
Mary got her education in the local school that her parents established themselves, as her parents felt that it was equally important for all of their children to be well educated, not just their son. After leaving primary school, she attended the Falley Seminary, where there was a strong emphasis on traditional gender roles. While a student here, Mary felt even stronger in her own defiance of 1800’s gender norms. Mary found her calling by reading her father’s medical books, which exposed her to a good medical understanding at a young age. Mary was able to attend and pay her way through the Syracuse Medical College where she graduated as a doctor in 1855. Mary was the only woman in her graduating class.
Mary was briefly married to a classmate but was divorced a few years later due to her husband’s infidelity. In 1860, Mary also briefly attended Bowen Collegiate Institute, but was later suspended for not wanting to leave the school debate team.
When the Civil War broke out, Mary volunteered as an Army surgeon until she was rejected from the service for being a woman. She was offered to serve as a nurse but declined. She instead volunteered as a surgeon for the Army as a civilian. Since there were no female surgeons at the time, she was only allowed to practice as a nurse. During her volunteer service she participated in the First Battle of Bull Run in 1861. Mary was also an unpaid field surgeon near Union front lines.
Mary was a devout suffragist and feminist in her life and not only knew that women were serving secretly in the military but was proud to see them serving. She did her best to keep their identities secret, going as far as to alter the press about some of the women who were healing in the hospitals.
In her service, Mary attempted to become a Union spy, but her proposal to the War Department was declined. She continued to work as a surgeon, in 1863 Mary became the first female surgeon to be employed by the U.S. Army, accepting a job as a Contract Acting Assistant Surgeon. She later became the assistant surgeon of the 52nd Ohio Infantry. Even though Mary in her service followed the Union Armies, she would cross enemy lines to assist and treat civilians regardless of what side her patient aligned themselves with.
Mary was later captured by Confederates in 1864 as a Union spy. She was sent to Castle Thunder and was kept there for several months until she was released as part of a prisoner exchange. After she was freed, Mary was assigned as the supervisor of a women’s prison, as well as the head of an orphanage.
After the Civil War ended, Mary was given a disability pension for muscular atrophy that she suffered while imprisoned. Mary went into several different professions after the War, working as a writer and a lecturer. Mary continued to advocate and support causes such as health care, temperance, and other women’s rights causes. She was heavily involved in the Women’s Suffrage Movement, going as far as attempting to vote in 1871.
For her service as a surgeon during the Civil War, Mary tried to earn a commission to validate her service. Since she was a women the Secretary of War ruled that there was nothing that determined a precedent for a woman earning a commission. However, they still felt that she deserved a commendatory acknowledgement instead if a commission. This led to President Johnson awarding Mary the Medal of Honor, making her the only woman to be given this honor. In 1916 the U.S. Congress performed an audit of sorts of the Medal of Honor recipients and revoked several of the honorees. Mary was among this revoked list. Mary was not made to return her medal, and sources state that she was later reinstated as a Medal recipient.
Walker never felt that she had not deserved her award as she was willing to cross into enemy territory to care for others when no man around her was brave enough to do so. Dr. Mary Walker was living in New York when she fell ill and passed in 1919 at the age of 86. She was buried in her hometown of Oswego, New York. Her funeral was said to be plain, and she chose to be buried in a black suit rather than a dress. Since her passing, Dr. Walker has been inducted into the National Women’s Hall of Fame, been pictured on a postage stamp as well as a quarter and has had multiple medical facilities named in her honor. She remains the only female recipient of the Medal of Honor to this day.
