Mary Edwards Walker, American surgeon and activist, Medal of Honor recipient (d. 1919)
Mary Edwards Walker, M.D. (November 26, 1832 – February 21, 1919), commonly referred to as Dr. Mary Walker, was an American abolitionist, prohibitionist, prisoner of war and surgeon. She is the only woman to ever receive the Medal of Honor.In 1855, she earned her medical degree at Syracuse Medical College in New York, married and started a medical practice. She attempted to join the Union Army at the outbreak of the American Civil War and was denied. She served as a surgeon at a temporary hospital in Washington, D.C. before being hired by Union Forces and assigned to Army of the Cumberland and later the 52nd Ohio Infantry, becoming the first female surgeon in the US Army. She was captured by Confederate forces after crossing enemy lines to treat wounded civilians and arrested as a spy. She was sent as a prisoner of war to Richmond, Virginia until released in a prisoner exchange.

After the war, she was approved for the Medal of Honor, for her efforts to treat the wounded in battle and across enemy lines during the Civil War. Notably, the award was not expressly given for gallantry in action at that time, and in fact was the only military decoration during the Civil War. Walker is the only woman to receive the medal and one of only eight civilians to receive it. Her name was deleted from the Army Medal of Honor Roll in 1917 (along with over 900 other, male MOH recipients); however, it was restored in 1977. After the war, she was a writer and lecturer supporting the women's suffrage movement until her death in 1919.
