Dr. Mary Edwards Walker is the only woman in U.S. history to receive the Medal of Honor [1].

Her distinction highlights a unique intersection of gender and military valor in a decoration that has been awarded more than 3,500 times [1]. While thousands of service members have received the honor, only one woman has ever been recognized [1].

Walker earned the decoration for her service as a surgeon for the Union Army during the American Civil War [1]. She was recognized for conspicuous gallantry and intrepidity while treating wounded soldiers on the battlefield [1]. Her work required her to operate under fire and risk her own life to provide medical care to those in combat [1].

As a battlefield surgeon, Walker operated in an era where women were not officially permitted in such roles. Despite these restrictions, her courage in the face of enemy fire led to her receiving the highest military decoration for valor [1].

Her legacy continues to be cited as a landmark in military history. The award recognizes not only her medical skill, but her bravery in hazardous environments where she faced the same risks as combat soldiers [2].

Dr. Mary Edwards Walker is the only woman in U.S. history to receive the Medal of Honor.

The exclusivity of Dr. Walker's achievement underscores the historical barriers women faced in military service. By remaining the sole female recipient among thousands of awardees, her record serves as a primary historical marker for the evolution of women's roles in combat and emergency medicine within the U.S. military.
