However, Mary's life was more than just a medal. Not only was Mary a leading suffragist, the first female surgeon to serve in the United States Army, and an advocate of women's dress reform, she was a woman who put the lives of others before hers. She sacrificed her personal happiness, her comforts, and her reputation in order to fight for the ideals she believed in, both during and after her service in the American Civil War. Mary was a nonconformist in every way, refusing to bow down to society's establishments. When society towered above her, demanding her to surrender, Mary planted herself like a tree and stood her ground. Mary's life is a testament to the idea of selflessness. Today, many Americans stand on her shoulders.
